I'm a novice when it comes to economics, so can someone please help me out with my thinking. Let me start off with a warning that this is a long post and my thoughts are all over.
Donald Trump has just become the next president of USA and looking at US/DXY the dollar has really surged, with experts warning us that we should brace for a strong bull under Trump. Looking at some of Trump's policies during the campaigns, i fail to see where real growth will come from.
1.) He definitely can't bring back manufacturing jobs from the likes of China and Mexico due to the low cost of production in those countries and even if he did they would become too expensive to export. We can therefore conclude that manufacturing expansion will be at a minimal.If he were to engage in trade wars with China, the US will be the victim as China is the single largest holder of US treasuries and if they were to damp them only God knows what would happen.
2.) He has promised tax cuts and less banking regulations. How does he plan on reducing debt to GDP ratio by doing that. The government will basically collect less in taxes. Every time a republican has taken over the oval office, the US economy shrinks(Reagan is an exception). The only winner here are the banks as they shall be able to report improved profits.
3.) By investing in infrastructure expansion, he would be creating thousands of jobs especially if he were to build the wall (though i wonder who will be the workers if Mexicans are locked out

). However their debt to GDP ratio is about 104% which clearly needs to be controlled if another recession is to be avoided. So how will the projects be financed?
USA is now becoming a services nation rather than a manufacturing one. Therefore the real winners here are banks and Wall Street. A strong dollar is not the best thing for US at the moment as it would hurt their exports and increase their trade deficit. In light of this, i'm i wrong in foreseeing a weaker economy come next year like in April once Trump's policies become clear and hence a weak dollar. With no meaningful growth in world economy and the rise of populism, the best thing is just holding cash or buying gold.
Is my thinking wrong in any way?
One more thing i forgot to ask. What are the capital inflows from companies repatriating their profits expected to be invested in other than treasuries? Does that really help real growth.
