Maybe we shouldn't be 8 billion
Because that is what it boils down to, either low class people from your society are chosen or some other people over there.
With the other people over there, good luck! because they sure as hell don't want to stop living.
As for your own lower class, good luck! because they already see that the people in charge are massive hypocrites(i.e. in order to stop climate change we need to reduce air travel! Oh but we all need to take private jets to the conference in Egypt...but our work there will more than make up for the carbon we use...)

Are you suggesting that one's perspective cannot change in 20 years or that he should kill his kids?
Rules for thee, not for me. Money is privilege and they think this puts them above the standards they wish to impose on others.
Emissions rise because of demand, and for the past 20 years, that demand has been a result of rising economies (e.g. China), and to a lesser extent growth in the Western world (through immigration). Emissions will keep rising until that quells. Fortunately, it's projected to in 100 years or so, but ending that sooner is possible and warranted. We can achieve this with universal access to contraceptives, and by lifting countries out of poverty more rapidly.
I mean nobody creates the rules except us.
The "no rules" mindset is exactly what brought us in this position. We could be 30b actually, maybe more, there are no hard limits if you discard every variables...
The fantasy from the greens is that Westerners are "consuming more and more". Really, there are just more people consuming.
