Both. Some of the provisions I mentioned are from the 2017 TCJA and stay in place under the OBBB, and some are new or extended. But the key issue isn’t whether the OBBB adds new tax breaks for the rich it’s that it extends and preserves a structure that already favors them.
So even if the top tax brackets stay the same, the bill keeps in place things like, The 21% corporate tax rate (down from 35%) Lower tax rates on pass through income and capital gains
No changes to how the ultra wealthy avoid taxes through trusts, real estate loopholes, or carried interest. And to top things off, it cuts funding to programs that disproportionately help low and middle income people, like Medicaid. So the overall effect is still tilted heavily toward the top. You can’t just look at “what’s changed” only, you have to look at what’s protected and who benefits from that. I’m not a dem either, I don’t think any politicians truthfully care about us.
