You need regulation to protect the people from one and another, protect people from companies, protect companies from other companies and yes in some cases protect companies from the people

The regulations FDR put in place gave you a middle class, without it you would still have rampent poverty which we saw in 1905, where "capitalists" (aka the very rich) were doing splendig, all the rest were standing in a food line.

Do away with regulation that's absolulete, not working or just plain wrong, but keep and refine the regulation that works.

a great quote from The West Wing (a series that every American should see at least once, think I've seen every episode 5 times by now:-) :
"we have to say what we feel, that government, no matter what it's failures in the past and in times to come for that matter, government can be a place where people come together and where no one gets left behind. No one... gets left behind. An instrument of good"
work towards that goal, step 1 make campaign donations by companies illegal (it's called bribery), step 2 make the government affraid of the people, something that is so not the case in the US
