Yes @patriamreminisci, interesting speculation ...

"... doesn't seem to kill anyone except senior citizens."

... but we might agree that the elderly ...

"... drag their economic growth down ..."

... is a much larger problem than just in China. Much of the Western world is aging steadily, with the steadily declining birth rates over decades. Leaving the younger generation to feel unduly (and "unfairly"?) "stressed" by the requirement to pay for all of the social contracts already in place to care for their elderly.

My prediction? It will be a much bigger problem than just China in future deliberations about what to do with all of "the useless eaters, with a duty to die ..." (an old quote from a former governor of Colorado ...).

We'll likely all find out soon enough.
