There are certainly regulations that hinder more than they help, but I haven't seen much to support the notion that these constitute the majority of them. If regulations in general were harmful to large businesses, I don't imagine they would spend so much lobbying against them.
As for the increase in costs, this is contradicted by what we see in nations with public healthcare. A private system of health insurance is far more expensive, due to:
A.) The point at which the number of customers who can't afford insurance outweighs the gain from higher prices is high enough that it leaves millions of people unable to afford care.
B.) The fact that it gives hospitals incentive to suggest or perform the most expensive treatments, rather than the ideal ones.
C.) The fact that it discourages individuals from seeking preventetive care, and the cost of treating the problems once they become too severe to ignore is most often greater than the sum of regular checkups.
As for the decline in profits, statistics across our nation's history (and in comparison to other nations) show that the spending of the wealthy is not significantly affected by high taxes until they reach a point far beyond what anyone on the left has suggested. In contrast, aid to those less fortunate has a large and positive impact on economic growth; the poor cannot afford to save, so increasing their disposable income leads to more economic acticity than the same increase would in the hands of the wealthy or middle-class.
You have made some solid points, though, and I respect your thoughtful reply. In hindsight, this video could have gone into a lot more detail than it did.
