Each brought completely different cultures, each deemed to be a threat to the fabric of American society in some way or other. Yet democracy in the US and economic development has been enriched by the diversity there, not weakened.

The French have got a long way to go, taking steps to actually acknowledge that racism exists would be good.
All of the groups you've mentioned ended up merging into an all-American middle class, which was and still is the backbone of the country. The cultural differences mattered less than the common values (law obedience, work ethic, respect for property rights, freedom of speech etc.). Everybody was covered by the principles set by the Founding Fathers and people at large accepted those. Same thing happened in France with the principles of liberty, fraternity and equality. Now it faces the problem of its own citizens, which denounce those basic principles in favor of their reinvented or even carefully constructed cultural identities. I wonder how much the attitudes and practices of these self-proclaimed rejects will actually enrich the diverse culture of France.
