It is way easier and quicker to make money by destroying a business than by building one up. It has negative societal value, so the people should prevent that from happening. It's also easy to do: introduce a sales tax on stocks held less than a specific amount of time, like two or five years. That forces stock owners to think about the need to keep the company floating for years or pay taxes.

It's not an untested theory: taxes on stock sales have existed forever, until the Reagan administration abolished them. We could see the results immediately in a huge wave of junk bond hostile takeovers that almost defined the 80s, financially.
