The title is a bit misleading. Everything has two sides, and after analyzing it broadly, it's clear that, true to his nature as a businessman, his economic policies tend to benefit the wealthy.
1.Tax Policy:
He proposed tax cuts amounting to trillions of dollars, including expanding the 2017 tax cuts and reducing the corporate tax rate from 21% to 15%.
2.Trade Policy:
He planned to impose new tariffs of 10%-20% on most foreign goods, with higher tariffs on Chinese products (at one point, up to 60%), and heavy tariffs on Mexican automobile products (even threatening to reach 200%).
3.Monetary Policy:
The Federal Reserve should lower interest rates to stimulate economic growth.

Let the man assume office before all this speculations and I think it's fair to access if a policy works or not after at least first hundred days in office.
Policies are still subjected to changes he can have some interactions with is trusted team and may be make some adjustments for now all this are propositions.
Also going by what you just wrote I would really like to understand how it benefits the wealthy. In addition Donald might be a billionaire but you hardly find any president of the United States of America who is a poor man or doesn't have wealthy friends, let's be honest. So thinking that Trump's policy would benefit the wealthy because he is one is unfair.
Correct me if I am wrong TAX CUT is something that would benefit everyone both the upper class and the lower class?
