I like China's Hainan(?) island plan for luxury spending. It will make Chinese spend their money domestically, even if it mostly flows into foreign luxury companies.Actually, luxury goods in China are hyper-taxed as they should be so when these youngsters buy these things, the Chinese government gets a lot of income for semiconductor and other research. I remember 10 years ago when I drove a bunch of Chinese FOB classmates to the mall to get their "essentials" and they remarked that every expensive name brand, we are talking $80 shirts, $300 shoes, etc... was so so cheap, like a quarter the price that they are in China. They marveled at these things and wanted to buy it all, while I told them that I could get 20 name brand shirts at Goodwill for $80 and every Monday was $1 day. If everyone spent money like me, China's economy would be a lot smaller. These irresponsible spenders have their place and use, but what is truly devious is when people try to use overseas shoppers to avoid the luxury tax in China thereby enriching foreigners while doing nothing for China. I hope Chinese customs catches all of them and imposes crushing penalties.
It will make Chinese authorities to have more data and transparency into the shopping habits. It can combat some foreign outflows, and start leveraging Chinese market power to influence luxury goods exporters e.g France etc.
While spending happens inside the borders the Chinese Gov would have more power and influence towards these backstabbing western countries who with one hand take China's money and with another slapping it back
