Guys here advocating for a massive defense spending increase, which area of spending can PRC afford to decrease? Industrial Policy and subsidies? Education and healthcare? RnD? Infrastructure?
There just isn't a way to not compromise future development, US military is built on top of these sacrifices and that has led to the current situation - it would have been worse(it will in the future) if not for US's historic gap vs ROW.
They can boost the aweful tax collection that China has. China only collects 19% of its GDP in taxes, all developed countries collect around 40% in taxes. What do Chinese people do with all the extra money they have? They buy useless real-estate or launder the money abroad to buy real-estate in western countries. Again a massive loss.
China is still not a proper developed country due to how low the government spending is. They need to boost tax collection, increase defense spending, increase spending on childcare subsidies and continue spending on all the other things. O yes, one more thing, impose a massive property tax to take out all the speculators.
