What the government is responsible for is ensuring EQUAL OPPORTUNITY FOR ALL it's citizens. And that the opportunities being made available are sufficient for them to live a reasonably secure life. That means that everyone gets the opportunity for a basic, and then higher education. Everyone gets a day's living wage for a day's work. Everyone gets equal protection from everyone else, under the law. Everyone gets equal access to health care and human services. Then, if people don't avail themselves of these opportunities, we need to address the reasons why. Are they mentally or physically ill? (This includes addiction.) Then we should find and offer ways to help them recover or at least contribute to the extent that they are able and willing. And if they are not able or willing, we should respect their humanity (and our own) by providing for them, anyway.
If we would ensure equal opportunity in this country, very few people would refuse to take advantage of those opportunities in whatever way they feel inclined. Not everyone wants to be a brain surgeon. Some people WANT to drive buses, and build houses, and fix cars. And we need people to do these things just as much as we need brain surgeons. So we should pay them a respectable wage for their services allowing them to live a reasonably secure life.
But this is not the system we have. The system we have is all about rewarding greed. It rewards money with more money. And it gives those who have more money than they need to live total control over commercial enterprise, which enables them to amass even more money that they don't need. Which they will then inevitably use to further rig and play the system to even greater advantage. And as a result, they get ALL the opportunities, ALL the justice, ALL the advantages, while everyone else is systematically being denied. And they are exactly the people who least deserve all this advantage, because they have proven their lack of social concern and responsibility. And this is insanely unhealthy for any society, because it is ultimately stifling, self-destructive, and unsustainable.
I don't give a crap about who's fault ignorance and poverty is until the opportunity to overcome them is real, and is available to everyone. And right now it is anything but.
