From the year 1900 to 1950, the US population doubled, roughly. From the year 1950 to 2010, it doubled again, roughly. However, for the last one hundred years, what did not double or increase at all? The amount of money in circulation distributed by the Federal Reserve remained at $1.6 trillion, the same it has been for a very long time.
Logically, that would mean everyone would have to have less to be able to survive with in savings. However, there are no limits on the amount of money one person or organization can keep. Our society is based on making a lot of money at its foundation, and it is natural for everyone to try to do it and to have savings. Businesses also have it to operate to try to provide for the needs of the masses.
What happens when the population quadruples? There is more demand for goods and services, which means companies have to provide for this, creating a need for large amounts of money in their possession. Also, though, higher demand can increase prices, and we have seen a large increase in inflation. You used to be able to buy coca cola for just 5 cents. Now you cannot.
Why does it increase prices? Well, basically, it has nothing to do with coca cola. The workers at the coca cola factory rent and buy homes, and the housing prices are increasing because people are willing to pay more. They will pay more because it's a necessary thing, and also it isn't easier or cheaper for them to buy land and build their own home. The same goes for the carrot farmers home, and the coca cola workers buy those carrots (so they need to make even more money). Due to other people being unable to afford their expenses, they raise the minimum wage, and then coca cola has to raise its prices to pay its workers.
What else happens when the population quadruples? There is an overall sense that society cannot possibly provide for all of the citizens of the population. Therefore, the poor are left unhelped. One part of the population that has money also has used it to continue to advance technology due to the free market, while the part that does not have any money has to live in poverty, resulting in a society that lives half in prosperity and half in extreme poverty.
