My comment did not compare those enjoying detached single family homes and large vehicles and flying to vacations with the richest few thousand people in the US and Europe.

Avicebron brought up inequality as the root cause.

DavidPiper indicated only the few thousand richest as the root cause.

Rayiner questioned if those few thousand richest have the means or capacity to reduce inequality.

estimator7292 responded that everyone has to help reduce inequality.

To which I wanted to point out exactly what would need to be sacrificed, because it would involve sacrifices among the top 10% to 20% of the world (constituting many on this forum) which those 10% to 20% would not even consider a "luxury". It is easy to claim a billionaire's private jet is an expendable luxury exacerbating inequality, but the reality is the bar is far lower than that (see statistics on energy used per capita, which can serve as a good proxy for which side of the inequality the lifestyle you might expect is).

That is why we are all mostly talk and no walk, because push comes to shove, we can't even get a sufficient fossil fuel tax passed to slow climate change for our own descendants, much less voluntarily decrease our standard of living solely for the benefit of others in the world.
