The entire system of finance is based on sham by constantly raising the cost of living so that savers have to turn to banks and other investment options to protect their base.
You must be mellowing in your old age as again we agree on some, just not all. And in this case the above we agree on, but for different reasons. The only way that it pays anyone to lend money is if they can convince the borrower that money today is worth more than money tomorrow. And that means you cannot have a deflating (or even stagnating) economy. (Nor for that matter hyperinflation which is also bad). That requires a very narrow range of "good" growth in both the economy and inflation, and yes Banks target that.
You dont work for altruistic reasons. You work for things (money being the common bond to get them). Same way with banks. They are not altruistic, they are out to make money.
