Really, who? I can't see the people in the 18th century using PV (or much electricity at all for that matter).
I think the real problem is that people somehow believe "the economy" is more important than the environment. Destroying "the economy" would have little to no effect at all on about two thirds of the world's population.
Fixing (and preserving) the environment will have an enormous benefit to the entire world population, with the exception of the very small number of people who currently profit from treating the environment as an infinite resource, or a static back-drop to our own civilization.
