Maybe, but I'm not sure it is positive for society. Plenty of people seem to be upset despite solid gains in portfolios.
Let's not miss the point of what I posted. META has had a historic effective tax rate of less than 15%. The Corp Alt Min tax (CAMT) caused it to report a tax charge of $16B in Q3. Put a 20x multiple on that and the company value got hit by $320B. To mitigate the damage, the CFO classified it as a "non-cash" expense and said “We continue to expect we will recognize significant cash tax savings for the remainder of the current year and future years,”. (I note it hasn't helped much as the stock has lost 20%. The C-suite stock sales in Jan and Feb look really good right now.). The OBBB didn't change anything in the CAMT (either through error, stupidity, or intent). So how could the CFO know that there will be significant savings in the future? Because she knew the Administration would give new IRS guidance on how the firm could avoid the tax.
So yeah, people can be very happy if they made money investing in stuff like META or PLTR or whatever. But they certainly aren't as happy as the CEOs. People can certainly believe Federal spending and costs should be controlled, but it is hard to justify mega corporations not paying a fair rate in taxes. The justification is always "jobs", but they are basically saying to the people "you should be happy to have a job, so pay your taxes" while the Corporate overlords make billions tax-free.
