Forty acres and a mule, plus inflation, to every African-American family who's ancestors were robbed of their life's work. This would go a long way toward restoring USA's moral legitimacy in the world, and help instruct other nations that tolerating slavery doesn't pay.
It could also do more for the current USA economy than trillions to too-big-to-fail bully banks.
When labor is not utilized fully in a nation, that effect is different from when oil is left in the ground. The oil can be pumped out another day, while a day unworked is gone forever. When less than all of a country's residents work fully, there's less stuff of value produced to split up between residents. Everyone is poorer.
When desperately poor, we are all likely to try anything to survive, even if it means taking away from others what is rightfully theirs. So in times of economic crisis, police budgets should be spared, if not increased, and, as done in Germany, the USA should shorten the work week so that everyone has a fair chance to work and earn, even amidst this recession.
Without moral leadership, the USA is left being nothing but the biggest bully on the block. Without jobs, the poor have no reason not to look after themselves at our expense. Without clear economic repercussions, slavery's found financially rewarding, and will continue to again worsen. Without borders, open to trade and investment, being open to people, nations themselves can and will be enslaved by vulture capitalists and such, as author John Perkins has described.
