Wow, your entire argument is just a bunch of democrat talking points/scare tactics strung together. Congratulations, now we all know you watch CNN on the regular, and apparently believe what they say.
This suite of reforms has so little in common with the 1980's policies derisively referred to as "trickle-down economics," it smacks of laziness on the part of those same blue-team detractors.
1. Let's start with some simple math: low taxes are Always a good thing, no matter the place, time type of govt. Taxes, be they taken by a king or by Uncle Sam, are money that is taken from individuals and families and theoretically put to use for the common good. We all know that even the best of governments is prone to acts of waste, malfeasance, even corruption, so the less that a govt needs to get its job done, the better. More people keeping their own money = Good. Doesn't matter if they are rich, poor or in between.
2. Liberals in the US love to vilify "the rich," and act as if their "richness" somehow impedes poor people's ability to make themselves rich. This, in fact, is not true. Not only do rich people encourage others to get rich, through hard work, great ideas, and smart investments, but they donate millions of dollars every day of every year to causes, charities, and non-profit organizations, such as hospitals, schools, libraries and museums, women's shelters, food banks, just to name a few. The Obama Administration actually took away some of the incentives for these people to do their good works, specifically tax write-offs. (The part of the income that they give away does not count as taxable income, thus lowering their overall payment to the IRS.)
3. Not only does this new law reinstate some of those personal incentives, it also gives businesses incentives to give away some of their money. To whom, you ask? Why, to their own employees! I guess they forgot to broadcast it on your channel of choice, but the very day the law was passed, some big, giant, evil corporations started giving out $1000 bonuses like candy. AT&T, Boeing, Comcast, Wells Fargo. It's more likely than not that You yourself give some of your own hard-earned money to one or more of these companies. Does it feel good to know that more of your money is going to be passed on to the guys and gals in the trenches than to the executives? Sure it does.
Why did that happen? Because the new tax law is structured to benefit companies that treat their employees well. It's those nifty write-offs again. Win-win.
4. I've asked an accountant, a banker, a stock broker and an economics professor, and they all say the same thing. The most powerful catalyst for growth to our (or any) economy would be to lower the corporate tax rate. In the US, it was 39% , third highest in the world. Sure, the Big Boys pay their cadres of bean counters to find and make use of every little loophole, to keep as many pennies as they can. But Mom & Pop running their diner or their laundromat or their auto parts store can't do that. So now we add the "simplification" part of the tax code reform. The loopholes disappear, everybody pays the same percentages, and the game is actually more fair now than it was before Trump showed up.
Bonus: if the corporate rate here is now 15%, and the corporate rate is 30% in Mexico, where is that widget company going to build its next factory? Corporate rates have been falling all over the world for the past 20 years, as countries strive to be more attractive to foreign investors, including those from the US. Now these investors are going to reevaluate their plans to move manufacturing to China (25%), HQ to Great Britain (18%) and distribution points to Brazil (34%) and Singapore (17%). And build, refurbish, hire and train right here in the good old US of A.
