Well it's been about the American Dream, the Land of Opportunity and all that. That requires a healthy economy as well, an economy where the middle class can work normal amount and get paid enough to have a normal life instead of working their asses off and be up to their necks in debt because the US economy has turned from a production based economy into a debt based economy and finally into what it is today, a Ponzi scheme.

To do that and actually Make America Great they need to start the factories again, to start production, to help the middle class. This is not about some internal politics, and it's not a Trump thing either (he is just more radical about it). They've all been trying to do this and failing because Capitalism and Liberalism ruined America a long time ago. Everything is for maximum profit and to maximize profit you cannot produce anything inside America.

They always try the craziest solutions as well. I already mentioned the tariff wars, another thing is the child labor laws which they've been silently loosening and we may not be that far from seeing American sweatshops with child workers.
Here's another food for thought: Have you ever wondered why unlike majority of the world in the 21st century, American women are being paid less than men?!!

These two will definitely make a lot of things a lot more complicated and I wouldn't be surprised to see a lot more wars if he wins.
