I can't imagine what would happen if you gave every citizen 10k. I would think there would likely be something akin to a revolution that may or may not result in a more robust economy. What the gov't is doing by giving so much money to existing companies that have already failed vs individuals with the possibility of failing is very much protecting the existing social structure of society.
Corporations like these are a hierarchy that generate implicit social striations in our society. By maintaining this regardless of the fundamental success of the product or competence of the management, they act only to preserve the class structure enforced by the institution and thus the stability of society in a configuration with marginal utility as regards productivity.
They're clearly ensuring their own future.
