Maybe they know about Malthus saying the same thing and being proven wrong?
We have had millennia of exponential growth. Slower in the past, and positive over the long term for a long time (since the bronze age collapse at a global level?).
Technological advance allows growth that is far higher than increases in resource usage. We often do the same thing on far lower resources than it used to take - sometimes far better.
The people at the layoffs side when growth doesn't meet the exponential quarter targets, or destroyed villages to build a few hotel chains that deplet water banks for their golf fields, haven't noticed it.
A real problem, but a different one. Bad decisions, bad government, bad distribution of resources. It does not alter the underlying trend which is better for the vast majority of people.
Only when that vast majority is synonymous with the upper class driving their Ferraris into work, or heli-taxis.
Almost everywhere in the world the standard of living of the average person is far higher than it was a hundred years ago, when it was far higher than it was 500 years ago, when it was far higher than it was a thousand years ago.
Thankfully, until it got messed up with MBA folks destroying society, and the planet, with late stage capitalism to meet those quarter targets.
