This isn't news to anyone that doesn't have their head up their ass (so it'll be news to a lot of people on this board). Properly, centrally planned economies have been outpacing the growth of more "capitalist" economies like the US for... ever.
Interesting note: These wars all over the world that the US is involved in, those ARE results of the capitalist economy. The big, greedy defense contractors are big and greedy and want more money, so they set their cronies up in government positions and off to war we go.
no.
Defense companies make a product, same as anybody else. They advertise to those who want to buy it, and convince them to hand over money. The bad guy here is not the defense contractor, but the government because the government is unique as a customer in that it can take money by force or make it at will. Nobody else can do that.
The only way to prevent this pattern is to completely change human nature (NOT GONNA HAPPEN) or strip the government of its power (more likely)
