Does that mean Ray Dalio is pessimistic about US prospects and thinks China will dominate the future?

But how does one invest in China without worrying about their capricious, personality-centered policies?

He's written (a lot) about his views on the future of the US and China here [1]. In general, he views them as the rising world power and the US being in (at least relative) decline. He seems about as well informed as anyone, apparently he's been involved there for 36 years and has personal relationships with high-level officials (I believe he even sent his kid to live and go to school there for a while). He also has a section on cultural differences - he expects them to continue to develop but doesn't expect them to become like the US.

As for how other people should invest there, I have no idea.

Ray Dalio is actually part of the minority of the Western FIRE sector that is not "fucked", precisely because Bridgewater has a strong position in China.

This is what "fucked" looks like: https://fred.stlouisfed.org/graph/?g=GoIg

Can you interpret this graph for those of us who don't understand the point?

Serious question.

It implies that there is a relationship between the fed balance sheet and performance of the s&p500, suggesting that a large part of the economic growth in America since the 08 economic crisis has been because of things like quantitative easing and not actual growth.

The interest rate is officially ~zero and effectively negative due to consistent QE (over $120,000,000,000 printed and given to banks every month). The Fed is practically paying the global financial system (in USD) to keep using USD.

There will be a massive reckoning as the global economy refuses to get ripped off by the Fed's relentless money printing. Yet the Fed is extremely hesitant to taper its QE policy, because that will detonate the domestic stock market.

It is not an exaggeration to suggest we are literally in the final years/months of the neoliberal economic order.

Trick question. What we are dealing with is a redefinition of economics with a substantially reduced emphasis on "money". Minimize how much of your wealth is exposed to the financial system.
