One of the most radical things any activist can do is take their money out of the bank. Deprive the world financial institutions of cash. Join a member owned credit union.
Today, credit unions provide checking accounts, loans, and virtually any service a bank provides. But credit unions are non-profits. Their investors are their members, not wealthy corporations. Their fees are lower. Where a bank might charge $28 for an overdraft, a cu might charge anywhere from $5.00 to $18.00, from my experience with the Resource Conservation Federal Credit Union (very easy to join) and Oregon Telco. Some credit unions have higher interest rates than most banks. They don't need to spend money on huge, deceptive billboards.
Credit union members would never, ever, go back to a bank.
History of the Credit Union Movement
The credit union idea is a simple one: People should be able to pool their money and make loans to each other. It's an idea that evolved from cooperative activities in 19th century Europe.
Since that time, the idea's guiding principles have remained the same: (1) Only people who are credit union members should borrow there; (2) loans are made for "prudent and productive" purposes; (3) a person's desire to repay (character) is considered more important than the ability (income) to repay.
Members are, after all, borrowing their own money and that of their friends.
These principles still govern most of the world's credit unions.
As the 20th century began, the credit union idea surfaced in Canada. Canada's successful efforts profoundly influenced two Americans: Pierre Jay, the Massachusetts banking commissioner, and Edward A. Filene, a Boston merchant.
The two men helped organize public hearings on credit union legislation in Massachusetts, leading to passage of the first state credit union act in 1909. Growth was slow, however. Fewer than 10 states passed credit union laws, many unworkable. The Massachusetts Credit Union Association grew slowly.
