Marxism is NOT an ideology about crying and complaining that things aren't fair, as we're told by the blue-haired freaks in Western Marxist Academic circles. These cowards burn down cities when people use the word "retarded" because they're emotional babies.
Marxism contends that capitalism was historically progressive in its raising the Productive forces over feudalism and slavery, modes of production in the past.
Marxism contends that capitalism (imperialism, the highest stage thereof) has outlived its usefulness, that profit-seeking cannot take us to higher stages of production, since profits are always collapsing, due to competition (good!) ... soon we'll need to swap out the desire for exchange-value and replace it with use-value.
Rational production according to the needs of society rather than the irrational production according to profit-seeking, especially as competition inevitably produces thinner and thinner profit margins, until all costs approach the cost of energy, which should approach zero as we continue Nuclear Fusion Energy research.
