Besides that I'm all for strict personal liability for the execs and the investors of the companies they invest in. That's of course the exact opposite of the way it works right now but that actually institutionalized externalization, one of the key issues with why the world is the mess that it is.
Corporations are fine, limited liability corporations are not, I'm becoming more and more convinced that they are in fact the root of all evil because they allow the erection of financial 'diodes' that allow you to partition your stash from your liabilities and the two should always be linked. They are a very effective mechanism to allow people to screw over society and claim it's all perfectly legal.
