Professor Philip Kotler is a big thinker, check out his new book: Democracy in Decline: Rebuilding its Future.

Here is one passage from the topic of this strong book:

There is a disturbing interaction between Capitalism, our economic system, and Democracy, our political system.  Features and trends in our Capitalist system are doing great damage to our Democracy.  The major problem in our Capitalist system is the growing level of income inequality.  There will always be some income inequality but it has moved to a level that is corrupting both Capitalism itself and our Democracy.  Capitalism is doomed to grow at a much slower rate because most of the gains in income are going to the 1%.  During the recovery from the 2008 recession, income of the top 1% increased by 31% but just 0.4% for 99% of Americans.  A great number of our workers earn less today in real terms than they earned in the 1970s.  So Capitalism and capitalists are dooming themselves by not paying higher wages to our workers and opposing raising higher taxes on the rich, many of whom even pay a lower income tax rate than their own office and factory workers.
