communism: From each according to his ability to each according to his need
capitalism: From each according to his gullibility, to each according to his greed?
that's not even close to the truth.
First off, communism requires a huge murder count to get properly installed. Then it needs more murder to keep it in place.
Russia, while it was still a "thriving" country, had lines for the very basics of life, and frequently people went w/o.
Why?
No matter how hard you worked or how good you were at what you did, you didn't get one pea more than the other guy that sobered up long enough to "stand" in line.
Do you want to rid the world of capitalism?
If so. With what? Again, keeping in mind that communism and socialism are failures.
