> Say the US government issues a bond, some bank buys it, and eventually they sell it to the Federal Reserve. The US government has the same debt, and it seems to me that the only thing that has changed is that the bank now has cash where before it had a bond.
This is mischaracterizing the situation. It actually is: 1. A bank buys a newly issued bond; 2. The government spends that bond money on the private sector. 3. The Fed buys the bond by changing the values in its database (i.e. "printing money").
The best I can do to explain MMT is this:
1. The government spends as much as it wants and collects as much debt as it wants.
2. The government plays a game of chicken with the private sector (including other countries).
2.1. As long as everyone plays along, its a ponzi scheme that spirals upwards until it hits a ceiling (hyper inflation).
3. Meanwhile, until it hits the ceiling, it creates "manageable inflation" and/or deflates the rest of the world's assets.
3.1. As long as the rest of the world plays along (which it does), the extra cash funds innovation (i.e. the private sector) and improves quality of life world wide (i.e. better pharmaceuticals, cheaper computing, etc).
3.2. Meanwhile, in the US the "manageable inflation" is paid for by the poorest.
My personal thought: the world's interconnected market is so complex, that no one understands cause and effect (including the people making the rules). Currently, there is an emergent property of that complexity that the US, Japan, etc can "print infinite money" and some large group of people somewhere are left holding the bag worse-off for the US' decision, but no one really knows who this group is nor how much those people got fucked. Even the impacted individuals don't realize they are impacted because individually its a small impact, and innovation keeps improving their lives enough to not complain.
Hopefully a denationalized crypto (i.e. no ability for a single nation to print money) will help us simplify all of this to be understandable again.
