If my final hour finds me under other skies, my last thought will be of this people and especially of you. - Che Guevara

Capitalism uses force but it also educates the people to its system. Direct propaganda is carried out by those entrusted with explaining the inevitability of class society, either through some theory of divine origin or through a mechanical theory of natural law.
This lulls the masses since they see themselves as being oppressed by an evil against which it is impossible to struggle. Immediately following comes the hope of improvement — and in this, capitalism differed from the preceding caste systems, which offered no possibilities for advancement.

How can it be "mutually beneficial" to sell at world market prices the raw materials that cost the underdeveloped countries immeasurable sweat and suffering, and to buy at world market prices the machinery produced in today's big automated factories?

The road is long and full of difficulties. At times we wander from the path and must turn back; at other times we go too fast and separate ourselves from the masses; on occasions we go too slow and feel the hot breath of those treading on our heels. In our zeal as revolutionists we try to move ahead as fast as possible, clearing the way, but knowing we must draw our sustenance from the mass and that it can advance more rapidly only if we inspire it by our example.
