I think you need to read the tax law again. You seem rather confused by it or haven't actually run the numbers. Maybe you're trusting some sort of propaganda-publishing source? Let's go to the mat here. You say $200K-$400K. Let's take a single employee doc with a gross income of $300K and see what he's paying in federal tax. Let's assume this doc takes the standard deduction like 90% of Americans are expected to this year. Let's assume the doc puts $40K into a tax-deferred retirement account.
In the 2017 tax code, the exemption is $4,050. That starts phasing out above an AGI of $261K, which this doc is below. The standard deduction was $6,350. So this doc had an AGI of $260K and a taxable income of $249,600. What is the federal tax due on $249,600?
Well it's $46,643.75 + 28% of the amount between $191,651 and $249,600 = $62,869
In the 2018 tax code, there is no exemption and the standard deduction is $12,000
So AGI is $260,000 and taxable income is $248,000. What is the federal tax due on $248,000?
Well, it's $45,689.50 + 35% of the amount between $200K and $248K for a total of $62,489.
Your tax bill went down $400 on the same income. Now I'm not going to argue that's a significant drop, but you're going to have a very hard time arguing that's an increase.
Mine will go up because employees can't deduct work expenses. More than compensates for $400. I also pay more than 10k in combined state and property taxes. It's not as simple as the above calculation for many of us. Most docs itemize, or at least did.
