Since you asked...They can start by not cutting taxes for the wealthy and upper middle class (say $250,000 per year or greater for single filers - double for joint).  Get rid of some of the tax loopholes that benefit the higher income earners (and some of the middle class).  Do not get rid of the estate tax.  Lower corporate taxes from 35% to 25% but get rid of the overwhelming, vast majority of ways that the, especially, large companies use to lower the rate (loopholes, etc.) so that the large companies are paying at least the same rate as the small businesses.  Change the way some entities and people are taxed using the capital gains tax and make it an income tax.  Cut the military budget.  Get rid of all welfare programs and in exchange provide a universal basic income to everyone (this will never pass) which in the end would save billions to administer and stimulate the economy.  Changing the 401(k) is a pure gimmick.  Probably more but running out of space...
