What is the main problem facing China now? To get rich before the country gets too old

The other problem could be said to be overpopulation but that isn't the factor it could have been simply because unlike India they reduced family sizes so the population problems in China are not the same as India's but China is now paying a terrible price for forced reduction of Family sizes for so many years.

What is that problem?

Not enough young people to take care of the older Chinese people. So, literally they are trying to get rich before they get too old as a country. Because there are not enough young people to take care of the older generation now.

I'm not sure how China will deal with this but I'm thinking that they will let younger workers (like the U.S. except for Trump has done) by letting people in from other countries to help take care of their elderly Chinese citizens of all classes.

For example, here in California, people who take care of older people in Rest homes are often from Mexico and south of the border all the way into South America or from the Philippines and other countries outside of the U.S. So, many of the nurses and orderlies taking care of long term care elderly patients are from other countries originally either with a Green Card or recent citizens of the U.S.

However, because of Coronavirus less people are going to choose to live in Rest Homes here in the U.S. for obvious reasons because 99% of the Rest Homes were hit by serious epidemics of Coronavirus killing many of their long term patients. This isn't just true of the U.S. but also worldwide regarding Rest homes by the way.

So, in home care is going to be the next BIG thing here in the U.S. and likely around the world for the elderly.
