Every other country who has printed has been destroyed economically with mass inflation . Can we truly print unlimited with no penalty. So far the answer is yes . Everything we ever knew about economics has been rendered invalid so far.
Yeah, there is consequence. It basically destroys the middle class and the powerful of consumption.
Ten years ago, the minimum wage in New York City as I recalled was $6.75. Now the minimum wage is $15.00. Also ten years ago, if you bought a house in a good neighborhood for less a million dollars in NYC, now it is worth $3 to $6 million.
Many retirees living in these areas are forced to moved out because they are no long able to afford living in these areas. Their social security yearly increment adjustment received from government is minuscule. It is only adjusted one or two percent a year and many of them don't live in rental control housing.
All in all, it boils down to lifestyle. If you had made $100,000 ten years ago, now you have to make at least $200,000 to have the same lifestyle as before in the city. Most of the people I know working in the city make the same salary as ten years ago except software developers. Many of them can't afford to live in the city anymore. They have left to the suburbs near NYC. It is much cheaper living in suburbs. My cousin bought a new condo in NJ near NYC recently for only $600,000, but he commutes to work in NYC.
Everything is relative. Other nations also have the same problem too. They print out too much money. The more money they print out, probably the less things people will buy. This all leads to massive decrease in consumption power and impoverishment for many people especially the middle class.
The rich has hard asset. They are safe.
If you don't have hard assets like house or stocks, probably your lifestyle will degrade very fast in couple years. It seems the feds and the government are very desperate now. They are trying to inflate the economy back on its track. Last two months, they adds couple trillions to the economy.
