the US should change its tax system

So we look to the current tax system now and see that it is sucessful in raising revenue. We all may not like it but it is sucessful in doing its job. Lets first give a few overviews for the round, first of in order to affirm he needs to show you how changing it would remedy the "problems" not just say that its "complex" but actually show why its complex and how a change could remedy that. Also he needs to show a large systematic change not just say lets let a tax break expire or show a small change in a tax bracket percentage, he needs to show an overall systematic change. So lets move to my advocation. First of all lets look to all the benefits this tax system provides, it allows for the government to pay for things such as social security, roads, an army and so forth. I agree with my opponent in saying that this is the primary way that we raise revenue, so its a benefit that we do actually raise revenue. Second off this system is set up with proper incentives for starting businesses. This current system is set up with tax breaks for people to start businesses and even for having kids so there are alot of logical benefits to having this system. 3rd it is a benefit that we have a graduated tax system so that the wealthy pay a higher percentage, if we had a flat tax it would either be too high for the lower income families and drive them in to economic despair or to low for the government to make ends meet and not get much accomplished. So we see that the current system is for the most part working, and the old adage comes to mind if it aint broke dont fix it. Now to his case: He first tells you that its too complicated so we need accountants and that they often mess up. How ever to the first part of his statement there is no impact, it is not a problem to have a professional to help you. Your not mandated to have a professional help you, but you can choose to. Thats like saying we should change the health care system in our country just because you need a doctor to do it, and they make some mistakes. How ever that leads to my to the arguement that they often make mistakes. First off he provides you no source for this ridiculously high number, also the fact is if they make mistakes companies like H&R Block volunteer to pay the fees and if they made a mistake 96% of the time then these companies wouldnt be able to make money so they would be out of business. Also to turn the entire arguement, it is better that we use accountants because it provides jobs to people which will helps our economy. If we changes the tax codes into one which we didnt use accountants then the lose in jobs and the loss in tax revenue will cripple the economy and will negate any benefits my opponent can claim. He then tells you that we are in a recession so that this is the wrong time to use this tax system. How ever that makes no sense because we have been in recessions with this exact tax system and have survived them just fine. If we change the system there is no gaurantee we would be ok in a recession so that arguement turns on him. Also the fact that a change in the system would lead to the lose in jobs as i discuss above would further exacerbate the issue and therefore lead us deeper in to the recession. Then he tells you that tarrifs are bad, how ever thats not true because if we erase the tarrifs then yes prices may be cheaper but alot of people will be out of work. It would cheaper to buy stuff from over seas and that would drive american businesses out of business causing an influx in the unemployement rate leading to an economic collapse. This is why noi other country in the world has absolutely no tariffs on there imports. Its not practical and would leave us worse of by leading to the depreciation of our economy and dollar leading to us being worse off. Therefore because this system is by far the best one we must negate.
