When you say "paying the banks," what they really mean is paying the bank bondholders. They are basically the One Percent.

Deflation means a slowdown of income growth. Markets shrink, new capital investment and employment also taper off, so wages decline. That is what's happening as deliberate policy in Europe and the United States. Falling or stagnant prices are simply the result of having less income to spend.

No price is too high to pay to try to make the financial system go on a little bit longer. But ultimately it can't be saved, because of the mathematics that are involved.

What do the 5%, or the 1% actually use their money for? They lend it back to the economy at large, they load it down with debt. They make their money by lending to the bottom 95%, or the bottom 99%. When you give them more after-tax income, it enables them to buy even more control of government, even more control of election campaigns. They're not going to spend this money back into the goods-and-services economy.

More and more money is being extracted from of the production and consumption economy to pay the FIRE sector. That's what causes debt deflation and shrinks markets. If you pay the banks, you have less to spend on goods and services.

Mathematically, debts grow exponentially at compound interest. Banks recycle the interest into new loans, so debts grow exponentially, faster than the economy can afford to pay.

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.
