I continue to be of the opinion that many of our economic problems could be improved with more competition. (Depending on your definition of "problem" of course. The current state of affairs is fantastically profitable some.)
To understand how healthy a market is, ask 'how easily could a brand new startup innovate in this area'. If the answer is 'not easy at all' - then that thing is going to be expensive, rent seeking, and actively distorting incentives to make itself more money.
