Normally, if someone goes bankrupt, you wipe out the debt and get a fresh start. But that's not permitted with student loans. So the effect is to impoverish many graduates with very high debts.

When economists speak of money, they neglect that all money and credit is debt. That is the essence of bookkeeping and accounting. There are always two sides to the balance sheet. And one party’s money or savings is another party

Today, people are having to spend so much of their money, to acquire a house and to get an education that they don't have enough to spend on goods and services, except by running into yet more debt on their credit cards and other borrowings.

For many people, the mortgages they took out before 2008 are so high that they would be better off walking away from their houses. That is called "jingle mail," returning the keys to the bank and saying, "You can have the house. I can buy the house next door that's just like this for 20% less, so I'm going to save money and switch." That's what someone like Donald Trump or a real estate investor would do. But the banks are trying to convince the mortgage debtors, the homeowners, not to act in their own self-interest.

When you say "bank," a bank is a building, a set of computers and chairs and things. The bankers are the people running these banks. They're the chief officers, and they push the loans because they don't care if they go bad. For one thing, they may package these bad loans and sell them off to gullible institutional investors.

The United States Government has fought against creation of an international court to adjudicate the ability of national economies to pay debts.

Deflation is a leakage from this circular flow, to pay banks and the real estate, called the FIRE sector - finance, insurance and real estate. These transfer payments leave less and less of the paycheck to be spent on goods and services, so markets shrink.
