Young men are excess capital and excess capital must be destroyed in capitalism. The interest rate on money is guaranteed to be zero, the capital yield of an employed human is negative if the yield of the capital they produce is negative, i.e. unsold products that spoil over time. Thus we fire them, to avoid the negative yield of labor and instead hold onto zero yielding money. The unemployed still need to eat, so they bypass the division of labor and just take what they need. To avoid this cost, you must starve them to death or outright kill them.

A rebellion is an act to pass the negative yield of labor back to the owners of financial capital and land but all at once instead of slowly each year.

To prevent rebellions, the government subsidizes the owners of financial capital and land by paying welfare, a bribe to make the abandoned behave by making them navigate bureaucracy and blame them instead of the original cause of their dependency on the bureaucracy. This is a subsidy, because the cost is not actually paid by the owners of financial capital but by the portion of the working class that is employed so that they hate the recipients of their taxes instead of the owners of financial capital and land that that created and benefited from the class of artificially helpless people.
