First, where to keep your money safe, but away from corporate banks, that need to be bailed out with enormous amounts of taxpayers’ money when they inevitably fail because of their greed:
Mutual / building societies
Mortgages, savings accounts and (sometimes) current accounts; owned by their members.
Local co-operative savings & loan schemes: an alternative to loan sharks.
Invest in land co-ops, community energy etc. for a better return than from a bank savings account.
Second, alternatives currencies / means of exchange that aren’t issued or controlled by corporate banks:
Local / independent currencies
Use currencies that stay in your local community, instead of being sucked out by corporate branches.
Currencies (like Bitcoin, for example) controlled by blockchain technology, not corporate banks.
Let’s go a bit deeper – how about systems that don’t use money at all – so it can’t concentrate in few hands and it can’t be lent at interest.
It’s a way to trade – to buy and sell things – without official currency.
And deeper still. How about networking all local mutual credit systems globally?
Collaborative credit schemes could scale up and network to challenge the power of corporate banks to issue money.
