As someone who went from earning $25K to $85K to $300K, I have near-zero empathy for the tax bills that any American family making above $200K faces... Or any of the owner class that is coming out as the big winner with the new tax bill.
Here's the thing. If you're making $400K in CA or wherever, you're not middle class. You're an upper class worker. You still need to show up to the office to do your 9-5-5, or your 6-9-6, or whatever it is you get paid for. Your interests are not aligned with those of your CEO, or even the CEO of the shitty temp sourcing company down the street, who makes half as much as you do. But you are also not, by any means, middle class.
You can drop out of this rat race in five years of frugal living, and retire far more comfortably then the poor sap filling orders at an Amazon warehouse will after 40 years of back-breaking work.
