Let's look at food for a minute. There are very few people in this country who cannot afford to buy food - the ones who can't are usually begging on the streets. But how often do people die of hunger, even in the inner city? I've been there, and it doesn't happen often - because there are many charitable organizations that exist for the sole purpose of providing food to those who can't afford to feed themselves. There are also many extremely cheap ways to purchase basic food; there is a market for very cheap services, so entrepreneurs will seek that market out and find a way to profit off providing for that extreme marginal consumer.
If it works with food, why not education?
there is also government support for people who cannot afford to buy food. if you take government out of it, especially the fact that a lot of those charitable organizations are government subsidized (if only by tax breaks) you would have FAR more people dying from hunger.
And the government is analogous to a large corporation. It has costs and provides a variety of services and goods. It has governing groups that make decisions about how to allocate it's resources. I could keep going... But the government is LIKE a corporation (but technically is not).
corporations are legally required to turn the biggest profit it can. if a drug company has two researchers, one comes up with a cure for diabites in the form of one pill, and another comes out with a new device which holds multiple doses of insulin for easy carrying, they are LEGALLY required to sell the second product and never sell the first. the government on the other hand, exists specifically to take care of things that shouldnt have to turn a profit. the government (at least in theory) allocates resources towards the bottom so as many people as possible get enough to survive. corporations cut costs and wages and raise prices to allocate as many resources as possible towards the top, to line the investors pockets. now sure, if you vote in people who are former corporation CEOs and think government should be run like a business, it starts to resemble a corporations. but if you look at parts that still work as they were conceived, like education, social security, and medicare/medicaid government is pretty much the exact opposite of a corporation.
