Bank account is not a "capitalism totem" or "free market totem", bank account is a CREDIT from CUSTOMER to the BANK. You should know this if you put money inside. If bank crash, fractional reserve banking, money disappears.
Taxpayers SHOULD NOT repair bad banks.
Thats true, bank bailouts don't act according to the market laws, banks should be able to go bankrupt.
Investors that make profit by taking the risk, should pay for it if something goes wrong, and not the taxpayers.
But people that use their bank accounts mainly for transactions and not for interest and profit should not be affected.
Thats why we need to go back to the Glass-Steagall Act of 1933, the separation of deposit business and investment banking.
The anglo saxon separation system was abolished in 1999.
