Free market capitalism does go through cycles of boom, bust, and then boom again. Businesses go under and other businesses replace them and flourish. There is nothing "wildly unfair" about it, the system works on a principle of general supply and demand. What FDR introduced, was wildly Marxist Socialist, we are still burdened with his programs choking freedom and capitalism every day. As well as the Marxist Socialist policies of LBJ and now, Obama. With each, the freedoms we once knew are eroded away, and replaced with State Tyranny. We plod along and capitalism eventually manages to mitigate the damage, but it continues to stifle our freedom and ability to grow and prosper, like a noose around our necks.
You have clearly never read Karl Marx, not if you think the current ( or any US administration) has acted on his philosophy. Obama has shocked even his center-left supporters in the Democratic Party by essentially caving in to the demands of Wall Street, and their fellow travellers.
What was wildly unfair was that as John Q Citizen, you could work hard, be honest, pay your bills, and have your finances and your families future wiped out by the machinations of speculators and voracious bankers. These are the very events FDR sought to prevent, not because he was a "Marxist", but because he believed in captialism, but knew that in its then form, it could not survive. His programs had nothing to do with Marxism, and certainly nothing to do with curtailment of freedom. Just the reverse. With programs like deposit insurance, for example, individuals were "free" to bank their money without fear, and not haul it out at every concerning newspaper heading. This in turn meant that the banks were "free" to have more assurance in making loans, and increasing wealth in the community.
One can, in the simplistic belief system you seem to engage in, imagine that an individual is in control of all that affects him, and so is responsible for all that does. This may have been accurate in simple agricultural societies, but it is absurd today, when the actions of policy analysts in Washington, traders on Wall Street, workers in Shanghai, Islamic Mullahs in Saudi Arabia, or any number of diverse actors all have major effects on the world economy, and hence on you. FDR was one of the first in the US (a slow learner in this regard) to recognize this, and do something about it.
Captialism, before the reforms of FDR, and later the great social movements of the '60s, was indeed wildly unfair, as it was the law of the jungle. If you were a tiger, life wasn't too bad. If you were anything smaller, tragedy could be, and often was, around the next corner. You live in a comfortable corner of the world, Mr Boss- how to you think you would like it in a jungle? My guess is you would soon be hollering for the sort of "socialist" reforms that people have fought for over the years, and have given you a better life

Revolt? FDR was damn near not re-elected to his second term. His New Deal programs did not "save" the economy, the war did. One of the reasons the "Great Depression" is known as "great" and not just another depression, as we've always had periodically, is because of FDRs programs which damn near killed us.
FDR fought tooth and nail against industrialists who did not want any sort of government intervention in the economy. That's why the US was still stuck in depression at the time of Pearl Harbour, while other countries that had shifted more towards an inteventionist policy were doing better. WW2 was, of course, the ultimate vindication of Kenysian policy. The niggardly and controversial attempts at social programs in the '30s gave way to no holds barred intervention. True, this came in the form of a massive military program. But the effects were the same. And it proved that the depression could have been ended much, much sooner, but for the angst of the rentier class.
Social programs have never created a goddamn thing except higher taxation. The so-called "progressive tax system" has never helped the middle class, they are generally the ones to take it in the shorts with tax increases, to pay for massive Socialist reforms. Look at who Obamacare is going to zap? Not the rich people who can afford to pay for their own health care, or the poor people who are going to get freebies, but the middle class, who have watched their premiums skyrocket, if they even get to keep insurance at all. You're not a "friend" to the middle class, you are a Marxist Socialist who believes in State Authoritarianism. You people need to be drummed out of our schools and run out of our country, back to Europe, where you can tinker around with social engineering all you please, while we engage in free market capitalism and run circles around anything you come up with.... again.
If you were to take the time to google tax regimes over the years, you would find out that the middle class was indeed doing better in the past. In the '50s, what is considered now an almost golden age in America, the top tax rate for individuals was around 90%. National debt was higher than it is today (due to the "social programs" of expenditures for WW2), but it was not a problem. Needless to day, the affluent paying their fair share took a lot of pressure off the middle class. The middle class was doing damned well, and it was because they were supported by government services, and they had the disposable income to demand various services which then created employment. This is a good way to have things.
