A few things I would say.
1.) The "wages are the highest" is essentially meaningless because wages are not growing faster than inflation:

If I pay you a $1/hour raise in layman terms but your groceries, heating bill, rent, cell phone, all rise by that amount, at the end of the day you don't have any more money in your pocket.
2.) Poverty levels are still rising in the US, 40% of Americans can't afford "middle class basics" any more:

78% of US full time workers say they live paycheque to paycheque (so basically nill savings and things like a medical emergency would gut many Americans overnight).

3.) The Federal Deficet/Debt is exploding under Trump, he is spending sky high, but cutting taxes on the rich, we are seeing record deficets.

4.) Many top stock markets analysts state the current market is overpriced and over due for a downward correction in the coming two years. So if he wants to "ownership" of the stock market (which really a president doesn't control in the first place) when the going is good, he should also accept ownership when the going gets bad.
