I would not take the complaints of those 1-2 billion people at all. Because there are that many if not more that without the advancements and help of capitalist western society they would not now be alive. And those that were might well be in even worse conditions. Some even make the complaint that giving aid and supplying too much food the west is responsible for these people's situation, yet otherwise they'd not be alive. You want to ask them if they would rather they had never been? A social engineer, an academic might make the decision that their lives are too poor so don't let them be born. I bet they wouldn't choose that.
You seem to have forgotten my position on capitalism. I needs a serious surgery, not a complete overnight throwing away in the bin.
In the interest of making this reply short, the portion I have quoted is quite alarming enough for me to end further correspondence. Let me just touch on that what I quoted, in an effort to demonstrate how far away from rationale I believe you are now.
First off, not heeding the complaints of 1-2 billion people starving is borderline lunacy. Partly because the stable human population of the planet was less than 2 billion before the advent of Oil. So when you say you wouldn't heed these people, that is quite alarming, proportional to the staggering number.
Second, by the logic of "they wouldn't be alive if it weren't for us" (so you can't complain, and you won't have your complaints heard by me) can be applied to fathers who rape their daughters (worst case scenario for example). You're basically claiming, the level of suffering doesn't matter in the slightest when compared to the "gift of life granted". If you truly hold that belief and you didn't speak in thoughtless error, then you are overdue for some ethics and morality philosophy, or a visit to a psychologist. I don't say this in jest, and I truly believe you simply didn't think much at all when you made these statements, so thankfully I think it's just that, and not that you're some deplorable sort of person.
Third, "might well be in worse conditions".. Worse condition than starving? I don't understand what that looks like, but perhaps you mean't instead of 1-2 billion people starving/poverty, maybe only 100,000,000 in starvation/poverty. Then I would agree, we would have technically less people starving.
Fourth, you speak about asking those folks if they'd rather never have lived? I think this is a question more effectively answered when you ask yourself. Ask yourself if you would mind not existing, or starving to death along with a child in your arms in the same situation. This is an easy one to me, but I'll await your preference.
Finally, your whole idea is flawed because it's based on taking credit for their situation, credit for this amount of people (thanks to "advancements of a capitalistic western society"). When in fact the only "advancement" was the discovery of Oil that spearheaded everything else that sustained and allowed the growth of such a massive population that isn't getting it's life-sustaining portion of that discovery. All it's getting is the caloric luxury of allowing more people to produce. The worst part is, you won't take the blame for their situation even if you're not directly to blame - you don't seem to understand the moral imperitive of how physically easy it would be to end these folks' suffering, but doing so would require taking money and spending on things that the current economic paradigm has set very little value to. But until my prior statements are addressed, things like ethics and moral imperatives for other fellow humans could perhaps be a fruitless discussion until I know exactly the sort of person I am conversing with.
