The more interesting question is "Why isn't the whole world poor?" Poverty is the natural state of society, wealth is an exception.
And for "why we instead are beyond poverty", that is a most peculiar question to be asked to Hackers, crafters of tools, engineers, providers of solutions, efficiency augmenters.
And if you want to go down that road then I'm wondering why we aren't considering before you are born. Or that when you are born you typically have your parents, siblings, etc. Not nothing.
