Quote from CaptainObvious:
No, capitalism in and of itself is not the problem. However, when it is "cornered" as suggested by the OP, capitalism then becomes a Plutocracy, perhaps even a plutarchy. Under such a system a wealthy minority have disproportionate influence over the political process. In essence they are able to buy favorable conditions for the continued bleeding of the economic system. The system is not as much cornered as it is held hostage while the wealthy few extort the workforce. Give us your money, or we upend the system, eliminate all jobs, and basically bankrupt the country. The worker is faced with the decision to work for slave wages, or have no work at all. Hence, all the money flows upwards.
Not a soul with even a microscopic level of intellectual honesty can argue that what we are experiencing is not a Plutocracy. To argue otherwise, one must be so completely bias in their political views, practice such an astounding degree of willful ignorance, that they are fully incapable of having a rational discussion on the subject.
