French in Louisiana?

I’ve learned that french(including the cajun dailect) is spoken in the south but only by the elderly why isn’t the youth intrested in there culture to learn it themselves i mean i am indian and i cant imagine not knowing hindi and punjabi. So why don’t they revive i mean for a will it won’t be that usefull but eventually it will come in handy right?

I am from Louisiana and I am half Cajun French and Half Spanish Canary Islander (Isleño) and as for French and Spanish in Louisiana being only spoken by elders and not the youth is because….Well, back in the day, the U. S. government outlawed all languages but english and punished children in schools when they spoke it and jailed people for speaking their native languages. Unlike today where the country encourages people of all races to embrace and speak their native languages ( like spanish on everything, just dial any corporate number and press 2 for spanish). In those days it was punishable to speak their languages. This is why many Whites don’t speak another language. We were deprived out of what the "new" immigrants get to hold on to. Quite a shame. I think if we had to endure that, then it should be the same for the rest today. Its only fair.
