The rest of the world seems to be doing just fine without it. I mean as long as a company is properly registered etc that is. This is not hard to do and there are minimal legal requirements with both investors and the SEC equivalent. You can invest at any level. Its “regulated” in that there are laws to comply with, but anyone can invest into any company if they will take the investment.
The idea that i can only invest if i am rich enough is ridiculous.
