While we may agree on a general principle, the details matter, and these things are complicated. The exponential growth phase is when that kind of influence is felt greatest, because the early adopters are greatly outnumbered by the influx of new people. We can look to the internet becoming mainstream as an example, as well. Now that growth phase is over, and late adopters have much more pressure to adapt than the other way around. Immigrants today are also late-comers, not an exponential growth wave expanding the US population to new orders of magnitude. Therefore, the details may turn out very differently. This could have been a valid concern in the 1700s or 1800s, but it's much harder to make that argument now. Our population is saturated, and we need to understand the dynamics of decline and renewal to discuss the issues you raise.
