Kacy, trade is a two way event, putting a 45% tarriff on Chinese goods into the USA, when China holds 3 trillion dollars or more of US notes, can you imagine the ramifactions of this, the scary part of both candidates was the walking away from the free trade stance most of the world has been moving to over the years, you can't go back to the 1960's as much as some might like too.
EG the British car industry will start to feel the pain of Brexit soon, Nissans has announced they have put their expansion plans in Britian on hold waiting for the outcome of the GBR EU negotations, at present GB ships cars into EU as part of the EU , a 10% import duty onGB cars into the EU will crash this market, Spain and France will pick it up-, there are 20,000 jobs at risk in GB, be careful of what you wish for. I am a retired exporter/importer of perishables into Asia and USA, these export markets are essential for most countries, our exchange rate at the low 70' c made it possible into the USA , then it dried up as the rate went over 80.
