If in 100 years the government provided clothing, and I advocated privatizing clothing, you'd say, "Becuase poor people don't need to wear clothes!"
Where I'm from (in the US), many poor people _don't_ achieve a basically acceptable level of education, because the public schools don't ultimately serve them well for various reasons, and they drop out (or just don't learn but keep getting passed on through the grades). We're talking like high schoolers at a 5th grade reading level, for example.
So it's not like the status quo is a panacea.
