Just started this video, but honestly, fractional reserve banking isn't the problem. It's been around for over two thousand years. While the wealth it "creates" isn't tangible, it is an expression of trust and agreement between the parties conducting their business, so the idea behind it is real. Same with money; people know it's just an expression of trust. Lots of Ron Paul supporters and other people swear by the gold standard, but it's not like gold has a whole lot of intrinsic value either, it just happens to be something human society agreed to put a lot of value on. Anyway, if society simply went off what we could actually make or use, it would not have advanced technologically nearly as it has.
No, the real problem is with unethical loaners, speculators and all the bullshit financial instruments that have been devised in the recent past. The financial sector is just too bloated, and the SEC doesn't do a thing to regulate it (i.e. the fucking reason it exists.) Something needs to be done about that.
