Experience in government doesn't really amount to a hill of beans. All those politicians do is run their mouths and make decisions that they'll never have to be accountable for.
Businessmen like Trump have to take the consequences of every single one of their decisions. If he makes a bad investment he himself loses money. If he doesn't keep up with the competition his business fails.. But overall he has emerged a winner.
Running a country well doesn't take govt. experience.. all it takes it a lot of common sense.
The government isn't much more than an old boys' network. They go to their offices, do their talking, attend their meetings, then at 5:00pm they go home and never have to worry about their own welfare because their paycheck comes from Uncle Sam and he gives them all the best perks (paid sick leave/paid vacations/paid hoildays.. they even get to vote for their own pay raises!) and their health coverage is provided by Uncle Sam too... and when they retire Uncle Sam will take care of them too!!
They never have to worry about the poor folks whose taxes or fees they raised or whose programs they cut, or how high they raise the national debt..
