Not with immigration.

Immigration will take a nosedive under Trump.

That's not necessarily a good thing. Do the New Americans want the same things as the pre-existing ones? Are they as capable? Not just "in a few generations" but here and now? Are they even likely to be as capable "in a few generations"?

If the statistics aren't very wrong, it doesn't seem like a solution.

Indian Americans make the most money in America, I’m sure immigrants can be capable

“Making the most money” isn’t the same as building a society people want to live in

by all statistics, it is Americans that make the life in the USA insufferable: corrupt politicians, oligarchs, lobbyists, party leaders, and criminals (the ones that sell drugs and shoot people).

go to any county/state jail and try to find a single H-1B visa holder there... its all home grown foundational Americans, raised on McDonalds and Coke

Don't worry, Republicans are hard at work making the USA a pariah state and turning away the educated migrants who've been behind most of the innovation and research of past decades.

What, non-migrant Americans are not up to it?

The US has benefited quite a bit by being a magnet for some of the most educated and driven people from around the world. This is not a controversial take.

Now, legal resident noncitizens are being deported for having political views that oppose the ruling executive party. This is not normal in the US.

Immigration is a double edge sword. Sure, it brings highly educated people on the top end, but also less educated at the bottom curve.

and on balance it changes demographics dramatically, that also shapes US policy in the future. It will be harder for USA to continue to be bloody warmongering machine with Military industrial complex dictating the policy and bombing countries and blowing up civilians around the world.

Immigration isn’t risk free

You get your birth rates up, but you also risk alienating your native born population and electing far right morons into office

Jury’s out on whether a tfr of 1.0 of native born people is better than a tfr of 1.4 with immigrants

US birthrate is 1.6, really bad, but by far less disasterous and permanent as China's 1.

I Googled: china fertility rate 2024

A couple of reliable sources say: 1.7 births per woman

Where did you get 1?

No credible source says 1.7, the source that says this must be based on some kinda UN projection of 2010. Real TFR is probably around 1.0, in some parts of china it's below 0.7 (in the northeast it's around this number, in Macao it's 0.4). A lot of other countries are completely fucked as well and google pushes up UN projections from years ago (Like colombia UN projects the fertility rate to be higher in 2100 than it is according to the official numbers right now).
