Although why people think they are entitled to a free service (banking) I dont know. No one thinks a cell phone company should give you free service.
Because its not a free service. Its in no way similar to a telecoms company.
The banks are lending out more money than they physcially own and gambling it. Thats why I mentioned the fractional-reserve system. The banks are generating cash purely on the basis that we wont all try and take our money out because theyre massively overextending themselves beyond their physical assets and can only do that until people start withdrawing money. their entire business model reliles on us.
If everyone stops using a telecoms company then they simply stop making money, stop providing the service and go bust (with some minor overheads for contracts and wages/pension obligations). Banks on the other hand dont just go down - they have gambled our money so cant repay it. So they cost us money they didnt actually own (it was ours) but also then take down the entire wealth they generated on that cash they didnt own which will be many times the initial investment.
Banks are free because they only exist with our money invested. If it was simply a storage of cash system (which is how they present themselves) then they could justify a charge but theyre not. They lend the money we keep there out to other people at a profit.
Without us putting money in from the real economy they go bankrupt instantly... Kind of like exactly whats happening right now.
