These changes will last exactly as long as this administration, so it would be a pretty foolish business that makes long term investment decisions based on this announcement.
What are the odds right now this administration is still in power in 2030?
Well, in part you are correct but look how the billionaires set up Vance as the next "elected" boss right now - it is quite a lot in the recent media, how Vance single-handedly rescues babies at night while being blindfolded. I think these anti-people changes that are harmful to them, will remain. Trump is just the old dementia guy; Vance "my eyeliners are perfect" will follow after "winning" the next election. And then nobody will admit to ever having voted for him - and people will be very befuddled, almost as if an oligarchy runs the show.
It's a pretty foolish business plan to depend on wrecking the planet.
I get one small comfort knowing that Wall Street will be increasingly under water as the climate disaster progresses (remember Sandy?).
