Looks like we have a resident socialist/communist.
First of all, the so-called "robber barons" made your life possible. Yeah, they did some bad shit - they also did a lot of good. Without those guys, there would be no internet, for example - and you'd have probably died of diphtheria or some other horrid disease in your childhood. Forming institutions such as the Fed were acts of evil, I agree, but credit where due on all fronts.
Far more people benefitted from the activities in question than suffered from them. That aside, all things have their associated costs, including "progress". Had the bucolic life been actually better than that found in the cities, the industrial revolution would have fizzled. It boomed because people WANTED to participate. They wanted to because conditions in the cities, poor as they may be by OUR standards, was still better than those back on the farm. People are often pretty dumb, but not quite so much as one would be lead to infer by your assertions. There was nobody marching workers into factories at the ends of guns. They came of their own will. Conditions often sucked, but that was the nature of business in those times. You cannot judge them by current standards quite to the degree your words imply.
FDR's interferences with the market dragged the depression on for 13 years. Had he kept his mitts off, the crash would have been felt for maybe 6 months and we would have been recovered. The previous market crash... what was it.... 1920... don't recall offhand at the moment... Harding was urged almost to the point of violence to interfere. He steadfastly refuses, earning him the wrath of the money trust, but that crash, every bit as bad as that of '29, was fully recovered from in a few months. FDR was the penultimate American fascist.
