I wonder if it occurs to people who "try to fix what's broken" that things are as they are for a reason, and it might be a good reason, a series of compromises and hacks necessary to create a system that is far from perfect, but that more-or-less works.

There are no doubt many things wrong with our financial systems, but I suspect they'll be fixed by gradual evolution that maintains what works, and not by a revolution that seeks to replace what we have with something that sounds good from a naive perspective, but is in reality much worse.
