Your english is alright and I agree with most of what you said. Unfortunately the issue is with local police forces rather than Trump and what he is doing. Right now in most cities (including my own) protesters are being met with batons and tear gas rather than understanding and peace. In cities where police have met protesters with peace and understanding, anger has mostly subsided. What I'm trying to say is that the mobilization of troops by Trump is simply a response to the escalation set in motion by local police.
I'm not defending Trump as a person or as my president. If it were up to me, I would have elected someone else. Perhaps he could step in and stop this, though I doubt anything he'd say would resonate across every state. Each state has its own government, with its own issues, values, etc.
On the issue of unemployement/wealth distribution, this is nothing new. This isn't a Trump thing. Unfortunately it's an american thing. It happened in 2008 when the economy crashed and it will certainly happen again after Trump. The cold war instilled a deep fear of communism in this country amongst people who were alive in the 80s. As long as they are still around, socialized societal safety nets will continue to fail before taking hold.
