If you're only interested in growing generational wealth invest in the continued growth of the market and economy through passive market ETFs and similar, thats what Warren Buffett always tells people when asked.
You will have good years / decades and bad years/decades, but if you have 30 or 40 years of work ahead of you, the market has to grow or the US falls over, so invest in the market growing.
And if the US goes to war with china and loses, it will be moot anyway because you'll be a slave in their post-japanese-trauma sadistic vengeance story.
The lesson of history is that the investor class never loses if they're diversified and burrowed into the economy deep enough.
- An industry or a giant company falls over? Who fucking cares, you also own a piece of all their competitors who'll slurp up their market share.
- Inflation? More pieces of paper to count the same net value.
- Oil Crisis? You own Renewables. Renewable Crisis? You own Oil.
I'm a subscriber to the corporate takeover school of US collapse where they maintain the institutions as hollow shells, in which case, if you own a bit of everything, when everything consolidates to 10 megacorps, its good to own ever a little piece of them.
The diversified investor class has only ever lost when they get eaten by the local population or allowed a dictator to rise, and even then its a coin flip.
Your kids or grand kids will probably piss it all away anyway though.
