Trump has only capitalised on the discontent you mention — he has no solutions for most people.
Ahhh, you might misunderstand what The President, is. The POTUS is the chief executive of the federal government. They’re not supposed to have “solutions” for people. They are supposed to execute the laws congress passes… and in time of war be the commander in chief.
Until you learn what a president is, you’re going to be disillusioned.
They aren’t the “boss of the country” they don’t “run the country”.
You’re supposed to find your own solutions.
Responsibility is the price of freedom.
If you want to live in a nation where the the president finds solutions for your life, I’d recommend you try Venezuela.
