This is really interesting and I once heard about something similar in terms of a tax system. So say you have very high taxes, well as with most things the top 10/20% are paying 80% of the taxes. If you bump your tax rate too high you lose the top earner who end up leaving the country. This then creates a ripple of people earning a lot who all leave and you're left with very few top earners and high taxes. Not sure I am personally for low tax systems but it shows you how most things work best when you're in the middle, not at an extreme.
