" I just don't see a way out of the Malthusian problem (there will be more and more of the sorts of people who breed more, by definition)"

Why is that by definition? Even animals have more or less offspring, depending on the food offering/suitable habitat.

It balances itself out. In nature by starvation. But humans could find other ways. But btw. there are many many people starving and allways have been.

It is not like we are heading to a starvation crisis. We are already in it and always have been. The question is rather, of whether we can stop it one day and have all humans fed and cared for in a sustainable way.
