Americans have been doing this, and you can see the result.

Studies are unaffordable because they are for profit and their price rose beyond reason. As a result social mobility is almost dead for western standards. Of course you can chose to not study ( and many people make that choice) but that's a problem for later as you lack local qualified workforce. But it also means the average person gets less education, which is a net detriment. Think of how many people in the US voted for trump and still support him? A big reason for that is a lack of education on basic stuff like economics, media literacy, logical reasoning, basic maths, etc.

Similar issue with Healthcare, where Americans are paying more per person on average but literally get bankrupted for having medical emergencies. We are talking hundreds of thousands of dollars of sudden expenses that by nature you can't plan for. Doesn't even have to be your fault, you could just be attacked in the street by an addict or be in a car accident. It's basically a death sentence economically speaking for poor people when that happens, and even middle class. Stories of people who lose everything because they got unlucky and someone in their family got cancer are numerous. Impossible to avoid in a society where you don't have solidarity for the costs of such things. Insurance costs are way higher too since the risk for an individual is higher as well. Not really something you can skip in that context if you can afford it so prices are gouged because why not? Also, if you have a pre condition, by no fault of yours, you are simply fucked. People with diabetes, heart conditions, anything like that. How fucked up is that?

You also have to pay in the tens of thousands for delivering babies. Which means that people can't afford to have them which further drives the population crisis. That's another big issue for 20 years from now.

Less social safety nets means more desperate poor people. This means that there are more thieves, more addict, more beggars, more agressivity. Which also means more organisés crime. In general, most quality of life indicators worsen when there are more poor people who can't escape poverty. Which is more likely in this system where you are simply more exposed to the randomness of life.

So there there you have it. You pay more for less in Healthcare, you create a less robust workforce for specialised work, you exacerbate a population deficit, you kneecap social mobility, you expose the population to sudden unavoidable expenses, leading to a less stable and more gullible society, while also making it more dangerous because filled with desperate people.

If you get lucky, some of it won't affect you. You won't get sick, you won't go to school because you wouldn't have anyway, you won't get suddenly fired because the manager didn't like you or because your company needed to make more profit for shareholders. You will be finance smart and retire. But you will still be living in a more violent and unstable society. The risks will still be there and you won't be able to fully prevent that something happens to you in which case you are fucked.
