Why would President Trump START a War if it will mean he would LOSE his money and all the other rich people would to ? It doesn't make sense

I mean I can see him being president to have a feeling of more power and all but why would America want to start a War if it would make the top 10 percent LOSE money because it would be wasted in War and then we poor folks won't have a penny to spend towards them
Think about it...

War costs A LOT
Sure..They might be protected and have unlimited food supplies but why give up their Rich life over a War?
The Donald can't simply go to his palace in Florida if people are starving. People would be all over his houses in America trying to break in them.

It just makes no sense. If I were rich...I wouldn't risk losing all my money and freedom. I can see them raising taxes and becoming greedy and all but War would just mean instant economical downfall.
My theory is that he is controlled by his daughter or he simply is very inexperience with everything.

I can't fathom why would the Elite be wanting to risk all these problems? The 10 percent would be hurt as well...Meaning that Doctors and Surgen and Lawyers and such would suffer if their CLIENTS have no money to spend.

I know that Bush JR did start a so called War with IRAQ but it wasn't the same as what Trump did. It was NOT towards the Government of IRAQ but was for so called terrorists and WoMD
