There is no compromise with the left. Dr. Peterson is far too charitable towards them (which is crazy considering how vicious the left is toward him) Thomas Sowell has been writing for decades about how utopia is not possible, only tradeoffs are possible. We progress by understanding that the perfect is the enemy of the good, so we should aim to build a functional society understanding that there will always be imperfection.

Therefore its not surprising to see Dr. Sowell being very pessimistic about the future - he knows the left will not budge an inch and they will not stop until all the achievements of Western Civ are destroyed.
