They correctly point out nothing in that context: the West wasn't "allowed" to industrialize and pollute (as if China or anyone else could have stopped that process) it just did what it wanted within its own territories, as did everyone else. The West just figured out how to do it over a century before anyone else, and China and India are simply playing off of the West's initial advantage. One could argue, however, that China, India and other regional powers are being "allowed" to pollute because both were enabled by Western corporatism and its willingness to sell out its own citizenry and shift its manufacturing base to the third-world.
The elephant in the room here is not actually that human civilization and concomitant industrialization cause pollution. No, in fact it is overpopulation, and that is the sole province of the third world. Not that I see many willing to talk about that: no, it's always the United States that is the source of all the world's ills, even when that's just not the case. Were it not for the flood of illegal aliens crossing our southern border, the U.S. would be in a population decline (as is much of Europe.)
That said, you are absolutely correct about poorer nations having little vision of the future, other than trying to achieve a high-energy, high-resource-utilization Western lifestyle for as many of their citizens as possible, even if the collapse of human civilization is brought that much closer.
