Is it true that after all countries become developed countries, their ideology and morality will rise, so they choose to stay at home for development and construction when the country is down and out?

Spiritual civilization needs to be built. Spiritual civilization can't catch up with developed countries, and the standard of development is to pay equal attention to both material and spiritual. There is no necessary connection between going abroad and patriotism. There are not many modern masters of science who come back from studying abroad to engage in construction ~ what's the use of staying at home and doing something wrong ~
