Yes, different environments exclude and include some people, those who may be on the border of capability seem likeliest to be impacted here. That still doesn't mean that ALL people can learn calculus, given enough attempts to find the right environment for each of them.
Shows, also, the silliness of this argument. Some people can pick up calc at age 10 no sweat whatsoever. Others struggle mightily with the basics in their 30s. Should we as a society invest 1000x the resources in the strugglers to ensure they can achieve the same understanding?

There's no need for everybody to reach the same level of understanding, but I think the pandemic has shown the importance of teaching as many as possible the basic concepts of calculus. "Flatten the curve" doesn't mean much when you've never heard of integration. The same applies to climate change. People will have more faith in mathematical models if they think it's something they could have done themselves if they really wanted to (overly optimistic judgement or not) instead of some bullshit the so-called experts made up to bamboozle them.
