Conservative Republicans have actually criticized Trump's tax plan for not giving the wealthy a BIGGER percentage of tax breaks. Trump shrunk the savings for the wealthy, so they actually will get a smaller percentage tax break than the middle class. But Because the wealthy earn more money, they will get a lower percentage, despite that it is more dollars.

Whether the wealthy open a new factory, go on another expensive vacation, or buy a new Porsche, any of the above contribute to the economy and job creation. As opposed to $7 trillion in corporate assets sitting in offshore accounts, that Trump's tax breaks will draw back to the United States.
In less than his first year, we are seeing a 28% rise in the stock market, the lowest unemployment rate since 2000, an increase in factory jobs, and the erasure of the huge spikes in unemployment and disability claims that occurred under Barack Obama's 8 years. In addition (U.S. Border Patrol numbers) an 87% decrease in illegal border crossings, and a rebuilding of our military and U.S. global prestige.
Liberals don't want to give Trump credit, but those are incredible achievements by Trump, in less than one year no less! One can imagine what Trump could achieve without vindictive obstruction by establishment types on both sides.
