Well, I think all of those things are rather different.

The idea of universal healthcare isn't exactly revolutionary - the NHS in the UK and European healthcare mean that all people are allowed to be treated when they're sick, no matter their life decisions, because everyone contributes to it. Just as much as someone might make terrible life decisions (e.g. be an addict) and need extensive care, someone else may have a freak accident happen to them (e.g. be paralyzed in an accident) and need similar levels of care. The basis for the belief that everyone should be able to access medical treatment is that overall it makes for a healthier society (since people will access preventative care more easily), whether or not they have the means to do so. I suppose it's just also the idea that when it comes to essential things, such as medical treatment, it is a common human duty to take care of the sick and not condemn them to illness because they may not have made the best choices. Not to mention that those choices rarely happen in a vacuum. Environmental and societal factors count a lot and those are not always in peoples' direct control.

Also, what is a 'worthless degree'? I think, as a whole, more people should be encouraged to pursue technical or vocational education beyond school, because a liberal arts degree is not right for everyone for example, but quite apart from the fact that art school (which some people consider worthless) produces great artists who are arguably just as important for a culture and society as much as engineers or doctors are, there is value in education, in having a population that can think analytically, who are intellectually mature and a university education can provide that whether you do a 'worthless' degree or not.

I personally don't think anyone should just have free food or housing as a matter of right. I think generally people should be required to work and contribute to society before they are helped by it. But I also think there are people who suffer from the various maladies of life - abuse, mental illness, disability, sickness, a lack of opportunity - who need a helping hand. I have no problem being an able-bodied, able-minded person who works full-time and whose tax money goes to make sure that a mentally ill person is not sleeping on the streets, that a single mother of 4 children who can't sustain her family on her income has access to food stamps, that a family of asylum seekers who need time to adjust and settle are able to benefit from social housing. I think but for the grace of God there go I, and if something were to go wrong in my life, if I were to be less fortunate, I would want to be a member of a society that takes care of its members. That doesn't absolve people of personal responsibility, and people should be encouraged and helped to find long-term, sustainable, independent solutions to their problems, but what kind of person am I if I let someone become bankrupt because they get cancer or they are in an accident or they have been 'weak' enough to fall into drug addiction? If it were me, or my child, what would I want others to do for me?

So it's a bit more complex in my mind than just - be lazy and have free stuff! And I suspect it is for most people on Reddit too.
