Capitalism does have its (many) virtues, however it in its pure form isn’t a solid end-state solution for humans (in my opinion).
Whereas focus solely on the whole sometimes ends up diminishing the individual, focus solely on the individual sometimes ends up diminishing the whole. I think we need to find a middle ground.
We need to give some of these bankers a hard spanking (and not in a sexy way), too, for being so irresponsible with such large sums of money for the purpose of personal gain.
And the only way to 'spank' a banker is to force-ably take away his money, make it harder for him to make money, or make him incapable of making money for a period of time; each of these have its own set of consequences, too, for the broader society they bank in.
