Because that's the way it worked when America was great in the 50s 60s and 70s.... All the new b******* GOP can do is cut taxes on the rich they are totally bought off and you are brainwashed.
No, you are brainwashed. This new tax plans target is lower income Americans. Not only does it increase medical tax deductions, they also kept alternative energy write-offs for nonsense like electric cars. They increased the tax deduction for children and kept the ability to write-off school loan interest. Mortgage interest deductions stay the same unless you buy a home over 750K after the law is passed. Even still, you can write-off the first 750K interest.
Lower corporate taxes means the likelihood of jobs staying in the US. Lowering the capital gains taxes encourages investments such as the stock market which are hitting new records all the time since Trump took over.
It would probably help you sleep better at night worrying about what you have instead of what others have.
