3% annual economic growth in unsustainable

I will provide a rebuttal of this argument."The problem with a constant growth in GDP is that in such a globalized world you can't just expect other countries to let your country grow."Actually, you can. Globalization has actually helped economic growth - look at all of the gloabal financial institutions devoted to promoting economic growth: the EU (although somewhat unsuccessful), the World Bank, the IMF (although they have some destructive policies), the WTO, and the UN. Economic growth is almost by definition international. For example, the US depends on China for manufacturing, and China depends on american innovations to manufacture."It is also important to realize that just relying on companies to make or spend 3% more on average each year. It's just not all that likely that companies will constantly be innovative. (and lucky when they are.) There has to be some form of government interaction to make sure that there will be constant growth. This may include things like raising minimum wage, but you can't just raise minimum wage over and over again. What can be done to make sure that their is constant economic growth in a country of at least 3%?"There are several simple, uncontroversial solutions to this probelm. Government can encourage competition (through legislation, primarily the Sherman and Clayton acts in the US). Companies that have failed to be innovative, like Apple, recently, have been punished by the market."Finally, it must be understood that each time an economy goes up by 3% it is going up slightly more than last time. 100% 103%, 106.09%, 109.18027% 112.2754081% etc. This may not seem like much at first but it's going to add up eventually you're going to have to be adding 4 or 5 percent of what the income started out as. There has to be exponential growth."Yes, economic growth is essentially always exponential. World economies have been managing exponential growth over the past two centuries (since the industrial revolution). Before the industrial revolution, growth did not exist. Wages in Babylon were, in real terms, the same as wages in the Roman empire, or in 18th century Britain. Once the industrial revolution's surge in technology began, real wages and standards of living rose all around the industrializing world. This observation is known as the Malthusian trap, developed by influential economist Thomas Malthus (biography here: http://en.wikipedia.org...).One of my main arguments is that as long as technological innovation motivated by free market capitalism and globalization continues, so will economic growth. In every developed country on earth, technology has been consistenly improving. In 1500, it was the printing press. In the 1870s, it was the phone. In 1900, it was mass production. In the 1960s - now, it was the Internet. In the 1970s - now, it was personal computing. In the 1990s, and the early 2000s, it was the internet start-up. In the late 2000s, it was clever and convoluted maniputlation of financial markets (just kidding). Perhaps in the 2010s, it will be 3D printing.The point is that constantly improving technology has driven exponential economic growth. There is no evidence that it will stop now.
