Points of optimism for you:
You say the Left controls most of the institutions; the schools, the universities, the Media, Hollywood, the book publishers and most of Silicon Valley.
Our schools are failing and school choice is getting bigger every day. Trump may well end the Dept of Education.
The Universities are losing students and power – that means influence as well.
The old media is dying. The new media (Twitter, podcasts, etc) is ascendant.
Hollywood is burning and will probably disperse into other states as CA is too expensive.
The legacy book publishers are becoming more irrelevant every day and will probably go through a period of consolidation and reduction. New publishers are emerging every day and self publishing is a viable option for eBooks.
The Tech Bros of silicon valley are coming over to our side.
Sometimes, all it takes is a leader. Like Trump.
