Land sales were gonna be phased out as a source of revenue eventually.Mostly just land sales, which is tied to the real estate market. It was never sustainable to derive so much revenue from what is essentially land speculation. Sooner or later that bubble had to be deflated and it finally was.
If you look at the blue and yellow bars, then they are growing. Perhaps a bit less than pre-2019, but part of that is also due to deflation. Remember, tax collections are done in nominal terms, so is there is 0 inflation, then tax growth will be subdued. I personally would look more towards things like debt to GDP, where there have been mixed trends. Household debt has stopped its explosive growth (good) but general govt debt keeps increasing very rapidly (bad).
Looking at government debt/GDP is a overly simplistic view of things. Singapore, for example, has very high debt/GDP ratio but is very fiscally robust. To see the full picture you would need to read financial records, analyze where the money is going, and determine if the spending is for services, consumption, investment, etc. Something that this group deliberately leaves out to endlessly parrot austerity.
Frankly you would need a communist party-state apparatus to adopt a "China model" so that's not even an option for the US. Americans will have to find their own way.I think the danger to this is that the US perceives China in a certain way and it may not truly appreciate the underlying factors to China's success, and it certainly is in no position to completely adopt the "China model".
"protectionism, constraints on foreign investment" are categorically NOT a part of the China model, the US is learning the wrong lesson here if what the article says is true. ironically the US spent so much time slandering China that it has fallen for its own lies, and now they could be punished for it.
