You have that exactly backwards.
France did not force them to move to France. They came of their own free will, hoping to better their situation.
The responsibility to assimilate is on them.
Let me give you an example. Up until about 50 years ago there was blatant discrimination against Chinese, Japanese, and other asians throughout the US and particularly here in CA.
But, they persisted, assimilated, and worked hard. Today , if a community has a substantial asian population, many times a majority, housing prices are significantly higher than in surrounding towns. The real reason is that everyone knows the school system will be excellent, and crime will be low.
No, I think I was absolutely on target.
Have you ever been to France ? A more proud, arrogant, stiff-necked people I have never met elsewhere. Geez, they won’t even speak French to you if your accent isn’t perfect.
Assimilate ? French society will never take in the Algerians a true Frenchmen, whereas here we take in all as true Americans over time.
To be a true American is to believe in certain things; to be a true Frenchman you must be born such.
