Like someone else said here, it funnels public money into private profits. What I do not get however is this system only furthers inequality which is going to snap the system at some point to the detriment of all, including the billionaires who will increasingly be in a hostile environment. Why shit on your own doorstep when you could make it better for all including yourself and your family. Really foolish thinking but oh well, as really, we seem absolutely committed to this dark path.
