True, but we live in the age of technological capabilities beyond the dreams of people of the past. We have metamaterials. And we can't fix poverty? Our ruling class chooses not to fix poverty. They like it, they enjoy it.
Most rich people make their money by exploiting those poorer than them, one way or another. Poverty will not end until we take power away from the people who profit off of those disparties.
Unfortunately, nearly 100% of Republicans and the majority of rich Democrats don't wish to do that. They think it's their right to make money off of charging rent, forcing poor people to take out loans, and exploiting workers just because they don't have capital.
