You can study Computer Science while also learning a bit of art history, or architecture, or psychology, or the sciences, or business, or...
And doing so might even make you more valuable to your employer, to yourself/your family, and to society.
> You are a burden on society if you don't have a productive job paying your own way... We believe is education required to be productive, so we subsidize education to get more productive people in society.
This mode of thinking is a great way to churn out lots of well-behaved, competent corporate employees. From this viewpoint, it follows that the path to the upper class is reserved for the already-rich.
So what?
You are not a burden just by not having a "productive job, paying your own way". You are a burden if you deny people their essential human dignity, by forcing them to conform to your vision of what they should be in order to eat. You are a burden if you take for yourself a surplus and do not use it to supply those with a dearth. You are a burden if you lie, cheat, steal, and assault. You are a burden if you do not respect and appreciate the hundreds of people working in harmony who helped each other to ensure you survived to adulthood with enough education to write your own opinions.
If all you do is sit on a couch with a cannabis vape and a game console, you're no burden to me. Some people keep house cats, and have no problem feeding them without getting much of anything in return. A "non-productive" human may yet do something. It might not be great, but could be at least marginally useful, if we allow them the time for their calling to mature and motivate them to action. Or they could just be a dud for their entire life. I don't really need to make a monkey dance in order to throw it a nut.
I don't particularly need you to take care of yourself. I may even be willing to pitch in with others to take care of you, on the conditions that you first do no harm to others, and then that you give back in whatever way you feel you are able. But that generosity only extends as far as what I think you may need. If you want something extra, you're going to need to give a little more before you get it.
We are way past the era of "no work; no eat" edicts. Thanks to our machines, we don't have a labor problem any more; we have an information problem. The systems in place for connecting creators with consumers, to everyone's mutual benefit, have never been entirely adequate, and haven't scaled very well to a world of 7.6 billion people.
As a member of society I need you to take care of yourself. You are a burden on society if you don't have a productive job paying your own way. We provide a "safety net", but the less who use it the better. Too many people using the safety net will make society break down. We believe is education required to be productive, so we subsidize education to get more productive people in society.
Or to put it simply: If you love art, get an art degree.
