You spend many words telling me I a ignorant but you agree with most of my economic points.  Imposition of tariffs will increase prices.  American manufacturing has withered to the point where it cannot supply our needs, and that tariffs will encourage long term development of American manufacturing.  Your reference to Cat fails to take into account that imports of heavy equipment have seriously eroded Cat's market share.  Within the US, they could regain market share.  It is not clear that countries targeted with tariffs currently supply large market opportunities for Cat.  Moreover, there will be no trade war, because countries like China could not survive without their massive export engine running full steam.  Trade war between countries of roughly equal dependence on trade is possible.  In the current world situation, some countries, e.g. China, have based their economy on export.

If you choose to comment, please stick to ideas.  Don't waste my time with personal attacks.
