In a "monetary system"? Is there any other system around except a monetary system? Does anybody in the greatest Country in the world still doubt capitalism? With capitalism comes graft, greed corruption and the freaking freedom to become rich and successful. Would you have it any other way? Why do we have this discussion every time a left wing democrat gets elected? Capitalism might have it's faults but surely even the self centered generation understands that socialism makes everyone equally miserable and poor and dependent on despots who live in luxury.
To be more specific, it is the kind of monetary system that is important. For example, some time ago, there were some monetary systems that didn't allow loans making interest. That is different from a monetary system which allows interest.
The there have been monetary systems based entirely on some physical item, such as gold, shells, cattle, etc. Monetary systems based only on bookkeeping are quite different.
Then, within monetary systems based on gold, some kept their coins pure gold while others mixed more and more of other metals into their gold coins over time.
Of course, we could imagine a large number of possible monetary systems that no nation has ever tried out.
On your other point, the international corporation system in the United States is quickly making it more and more difficult for an individual to become rich. The giant corporations can easily destroy a small business started by an individual, and frequently do.
So we no longer have a system in which it is as easy to become rich as it was 50 years ago, and the situation is getting worse.
If you carefully do some research to discover what us really going on, rather than what the ideal should be, you will become alarmed.
