There's no good guys and bad guys in this. You must understand that unless a loan is issued with a zero or negative interest rate, it will always have a net negative impact on your balance. Where else does the money to repay the interest come from?

This is especially true with central banks, where every € you receive comes with debt attached. How do you repay the interest on those debts? You have to borrow more €'s from the central bank, which also come with more debt attached. And so your debt burden increases exponentially until you're crippled by interest repayments. It is mathematically impossible to repay debt in these circumstances.

It takes two parties to get into a mess like this. As the old saying goes, "if you owe the bank $50 thousand, you're in trouble. If you owe the bank $50 billion, you're in it together".
