I read his book. I agree with most of what he's saying except for two issues; income inequality and China.
I don't feel like he's looking at income inequality in a way that's meaningful to the broader economy. There are lots of metrics here, but to be very brief... our poor people are fat and armed with the latest technology (cell phones, TVs, appliances) and enjoy the comforts of developed world living (fridges, AC, clean water, adequate supplies). So if Elon Musk is a squillionaire, that doesn't necessarily mean anything needs to be systemically fixed IMO.
I also don't believe China will be the dominant world power we once thought. They have put themselves in an economic straitjacket over Covid. Their elder care is awful and their poor do not have the stuff listed above. Japan was in a similar position 35 years ago when we thought they would take over.
