Why can't France be self-sufficient and want so many immigrants?

Population structure and population aging, labor market demand.

1. Population structure and population aging: The population structure of France shows an aging trend, that is, the proportion of the elderly population is high, while the young labor force population is relatively small. This leads to the shortage of labor supply, which can not meet all the labor demand, and needs to rely on foreign labor to fill the vacancy.

2. Labor market demand: France's labor market needs to meet the labor demand of all walks of life, including low-skilled workers, skilled workers and professionals. In some areas, the local labor supply in France can't meet the demand, so it is necessary to introduce foreign labor.
