Mass Deportation Policies undermine American Labor

It's amusing to note that my opponent just debated a Libertarian Socialist, since one of my favorite debates was one where I was arguing for Libertarian Socialism...Alright, well, when I speak of undermining American Labor, I mean to say that increasing deportations will cost American workers more jobs, give them less bargaining power, and lead to lower wages than the alternatives of maintaining the status quo or of providing undocumented workers with a path to citizenship. You see, there are essentially three worlds which we can live in. In one world, which in the short term is likeliest to become a reality, President Trump will deport even more people than President Obama deported. This probably doesn't mean that everyone will get deported, but a larger number of people will. Another possibility is maintenance of the status quo. Or for the sake of argument, by status quo let's say that people who are currently in the United States by and large remain in the United States. DAPA and DACA wouldn't get repealed and people will be protected by those statutes. Now I know that it's a little more complicated than that -- again, Obama did deport many people himself, so in that sense the same rate of deportation would be the status quo; even so, the increased rate of deportation under Trump which is rather likely will not only be cruel to the people who are getting deported, it will also harm American workers as we shall soon see. The third possibility, which is unlikely in the short term, but which I do hope will eventually happen, would be comprehensive immigration reform, a path to citizenship. Each of these worlds get's progressively better, from the first to the last described, for both the undocumented and for the American nationals. Here is why:Contention 1: The bargaining power of workers to get higher wages/ benefits is positively effected by increased rates of unionization, and lower rates of unemployment. In other words, the more unionized a firm is, the more likely it is that people in that firm will get higher wages than a less unionized firm. Furthermore, industries that are more unionized than other industries have better paid workers in both union and non-union shops. This is because when the unions push up wages for their workers, other firms have to push up wages to compete for labor, and to keep unions at bay. This is born out by economic studies. For instance, according to a study by the Economic Policy Institute: "Unions raise wages of unionized workers by roughly 20% and raise compensation, including both wages and benefits, by about 28%." and, "Strong unions set a pay standard that nonunion employers follow. For example, a high school graduate whose workplace is not unionized but whose industry is 25% unionized is paid 5% more than similar workers in less unionized industries." [1]Furthermore, from the mid 1940s till the late 1970s, the Federal Reserve had a goal of maximizing employment, which it often succeeded at meeting. And while levels of unemployment stayed relatively lower, Unions were stronger, wages were higher, the working and middle classes were doing better, etc. This is because, when unemployment is lower, the bargaining power of workers tends to be higher -- the less afraid somebody is of getting fired and being unable to find a new job, the more willing that person is to push for a better wage, either at the individual level or through a union, at the collective level. [2] (a study which analyzes the wage effects of lower unemployment, though not specifically those effects from the 40s-70s)Moreover, during that same time, the floor on wages, the minimum wage, correlated to higher wages for everybody.[3] As productivity went up, the minimum wage went up at roughly the same rate, and so did average wages. However, the minimum wage peaked in 1968 at $8.68 in 2016 dollars, and by 1973, average pay and average productivity began to diverge: nowadays productivity is much higher than compensation. [4]Contention 2: Fear of deportation leads to lower wages for the undocumented and in turn, for American nationals: Now, you may ask, what does any of this have to do with immigration? Well, let's return to the three worlds.It is true that undocumented workers tend to get paid less than American nationals, however, the question which our immigration policies determine is really a question of how much less. You see, when there is greater fear of deportation, it is much easier for employers to exploit undocumented workers -- if you want the higher wage, or to unionize or go on strike, those efforts can be broken by ICE agents who can put you in a detention center, or worse, deport you. Now, this does not just mean lower wages for those undocumented workers who stay in this country, it also means, as we can observe from contention 1, that when the wage floor is lower, wages for most middle and lower income people go down. When unionization rates are higher in any given industry, that means wages tend to be higher in both the unionized and non union shops -- it stands to reason that the reverse is the case when unionization rates are lower, and one powerful incentive to reduce unionization rates would be deportation. But what if EVERYBODY get's deported, you may ask (without even thinking of the terrible humanitarian impacts).Well, first of all, even under President Trump this seems unlikely and highly unfeasible. We're talking about 11 to 13 million people, many of whom have children who are citizens. The most likely scenario is that mass deportations will increase, directly harming the deported, causing those who stay to fear for their livelihoods and their ability to continue to stay, a lower floor on wages, and lower wages for American nationals. Contention 3: Outsourcing is more harmful to domestic wages and employment than undocumented labor Not only does fear in American labor markets cause wages to go down. When undocumented immigrants are deported, the labor pools of developing countries, especially in Mexico and Central America increase. Whereas, even the undocumented workers in the informal American Economy may get paid around 4 dollars an hour, the minimum wage in Mexico is around 4 dollars and 25 cents a day (and it recently went up). Now, you have to ask yourself if you'd rather have somebody making 4 dollars and 25 cents an hour or a day? And, when you ask that, keep something else in mind: in a world of free capital movements and trade, it is quite easy for Multinational Corporations to ship jobs overseas. The more people who get deported, the more people can be hired at even lower wages -- indeed, at abysmally low wages, by American based Multinational Companies. For American labor, this is the difference between getting told, you might not want to push for higher wages because we can pay someone 4 dollars an hour, or getting told, you might want to accept the pay cut because we can pay the same person 4 dollars a day. It's the difference between being employed and unemployed, higher wages and lower wages.Contention 4: The best of the three worlds is dismissed as "amnesty"If undocumented workers can come out of the shadows, start their own businesses, join labor unions, bargain for higher wages, that won't only be better for them, it would be much better for American workers. This would mean higher employment, higher consumption, higher unionization and (another thing I'll address in greater detail in round 2) more revenue for social services.To be clear, my burden of proof is to demonstrate that deportation harms wages and employment for American nationals, but I can go one better and demonstrate that a path to citizenship would be helpful -- extra credit ...
