The mortgage industry imploded due to lending to unqualified buyers. That's pretty simple to stop. This goes back to regulation. It wasn't Washington that egged these companies on. It was their own greed. And as we all now know, greed in an unregulated market leads to corruption. So my view is consistent. Solid and sensible oversight on markets.

As for who gets to trade in the markets, it's a good question. Your point on airlines is actually to my benefit. Airlines would practice sensible trading because lower fuel costs help their bottom line.

I would look to limit hedge funds and similar types of investment vehicles. Basically clear out the types that want to push the price up 40% then sell at a high. Those are types that are causing worldwide struggle to the benefit of the very few and the very rich.

It may not be pure capitalism but it is better for people like you and me.
