US has the strongest economy in the world and it’s obvious that it is going to grow since its main competitors (Europe, China, Japan) have declined. (Think market share increase and capital increase, in terms of a company)

The main two problems that faced US economy in the last 60 years - energy and jobs, have been solved by US. For energy, US is now the largest energy producer in the world. For jobs, US has climbed out of the hole of threats from globalization, increased internal labor force and automation, by using tariffs, deportations, border walls, upgraded workforce via increased education, and splitting threat from its main outsourced competitor China.
