Millionaires and Billionaires didn't ever get rich by any honorable means. It's all "dirty money". You best believe that.
They fucked over somebody or a whole bunch of somebodies to get where they are.
Well, in the market, there are many instances where if you aren't willing to participate in the race to the bottom, you're going to quickly be replaced by someone who is. It is societies responsibility to identify these instances and correct them, not to sit back and shake our heads in disapproval as negative things naturally happen.
I think that any economy where growth is high is going to lead to inequality. In low growth situations, say, 0% or 1% a year, the average person who invests in the market "as a whole" can only expect to get back what they put in. You have to truly be meritorious to hope to get ahead, you have to beat the average. However, when the economy is growing faster than that, a spoiled inheritor can expect to do very little and not only maintain their wealth, but see it grow tremendously. Not based on any work they did themselves, or any special merit, but just on the backs of the naturally growing economy itself. High growth environments lead to situations in which people can simply snowball up huge amounts of wealth.
It has been noted for a great deal of time that, while you often see a man's neighbor doing twice the amount of work as someone else, you rarely see them doing ten times as much. But it's not uncommon at all to see one man have thousands of times the wealth. Again, I think this is due to our high growth economy. If you look at history in the light of my theory, it is really not surprising when these socialist movements start emerging:
In the early US, there was not much growth per capita. And there wasn't much wealth inequality either - we never saw anyone rise to the heights of Rockefeller. Some people may make more, but it was much easier to see back then that it was due to their own work. And there really wasn't much of a socialist movement either - indeed, the defining feature of the left, as is often pointed out by libertarians, was their opposition to government (it was kind of a stupid left, that opposed the government because it kept farmers from burning down banks so they wouldn't have to pay their debts). However, as soon as the industrial revolution happens, and GDP per capita begins growing tremendously, low and behold, first you get the Republicans lead by Lincoln who put the "man before the dollar", then you get populists, then Progressives and Socialists.
The common man could see that the system was no longer working. They could see that something was up. And so FDR came, and with his policies he was able to restore the balance and establish a new equilibrium. Marx correctly identified that the strifing social forces would overthrow the old system, however, he was wrong in his perscription for what that system would be. The worker's revolution was a success - Orthodox Marxists, on the other hand, were reduced to being simply an odd kind of warlord in underdeveloped areas that typically produce such warlords.
The modern Conservatives seem to believe that they can ignore history, that by sheer strength of will they can pretend that things are still how they were early in the Republic. But they're not. They're tearing down the system and merely rediscovering the factors that forced their ancestors to put it up in the first place.
