Park ave condos existed and were owned before you were born and have nothing to do with contemporary credit.
The rest is the same tired class warfare nonsense.
Everything anyone ever does in economic life changes the value of every commodity you possess, and plenty you don't possess. Is this a reason for no one else to be allowed to perform any economic action of any kind? It is not.
If one man lends to another to fund some new production, neither of them you, and the loan is sensible and makes economic sense and produces new value, then there is more value in the world after it than before, and none of that value is yours. Does that pick your pocket? It does not.
If two men agree to work together to make something, do so, and others like it and bid for it, and in doing so are drawn away from something else you work at or own or sell, does this pick your pocket? No, it does not. Buggy whip makers aren't robbed by Henry Ford. The value of their goods and services changes, but they had no prior right to those values, beyond their real usefulness to other men.
And you have the freedom to pick every commodity you want to hold or own, and to avoid any other. If you think one class of them is a bad deal, you needn't hold it, and you are not wronged in any way by someone else choosing to, even unwisely.
If some potential customer of yours goes to Vegas and bets on red and loses, and then can't buy something you offer, you have not been wronged by the house in Vegas, or by him. Because you had no prior right to the value of his goods. The bare potential that he might choose to do things that would benefit you more than what he did choose to do, is not an economic right that can be violated if that doesn't pan out.
You are not wronged in any way by modern financiers and their modern finance. Sometimes other free men will even manage to do stupid things that make everything harder for the whole society, because it is poorer for their mistakes than it would have been for more enlightened decisions. But that still isn't wronging you, because you have no prior right to other men always using their freedom wisely. It is their freedom, not yours, and they are not your slaves.
You need an attitude adjustment, stat. Also, you haven't got a conservative bone in your body and you are on the wrong site, thinking as you do.
That's a nice red herring, but that's not what happens when the Fed creates credit. To put it simply, my committed capital loses value when they do that. My long term investment in productive capacity is swamped by the speculative leverage fueled by cheap credit. As a producer I might get lucky and get an LBO, but it is much more likely I will find all my inputs costing much more, long term capital costing much more or unavailable.
