about the cyclical economy

If our banks create access to money in a way that drives investors and entrepreneurs, and if this money is simultaneously invested outside the real demand in a market economy, then an economy has been created which is due to an artificial demand and to artificial price increases as a result of where this money is first put into the economy.
We thus get economic cycles that do not always depend on, or reflect, where the market economy pricing and demand are of their own power.
Instead, it will reflect where the banks think they can best serve their interests.
When reality then catches up with these bloated economic conditions, we get a recession with less money in circulation, but with the debt remaining that is the cost of the money that was created and driven the artificial economic upturn in the economy.
In this way, companies and individuals pay jointly for the banks’ speculation.

Banks should work with asset management and lend money. But why do they get to create money in that process?
