In response to #24 -- Unless Communism adheres to the Rule of Law where individual Rights are safeguarded, an age of flourishing Communism will never be. And should Communism adhere to the Rule of Law, it would, by definition, no longer be Communism.
Capitalism has not screwed a large portion of the world's population, rather, it has enabled the population of the world to sextuple in a 150 years. It has raised the standard of living for millions, and those millions would not exist today had it not developed.
One may feel instinctively that one system is better than another. Choosing whatever system to run a society should, however, be based on fact, not feeling.
Whatever Capitalism's faults, (and I invite such a list) I'd suggest that its perceived "failings" are due to intrusive or poor government than any fault of the Free Market. More ills have been perpetrated by governments favoring industries through back door deals than have ever been caused by those competing in a truly level field.
Certainly fortunes have been amassed at the expense of the poor. That is not the fault of Capitalism, but a failure of government to safeguard the poor from theft by unscrupulous businesspeople.
The only fair system is one in where individuals may exercise their Rights. The exercise of Rights does not include "special rights" conferred by government to favor a given industry or corporation and manipulate the market. As bad as that is, that's a minor transgression relative to a government controlling all industry and distributing goods and services as it sees fit in the name of some economic egalitarianism.
Read The Communist Manifesto. Then read Capitalism: The Unknown Ideal.
