In at least some parts of Canada, for example, there are tuition credits which you can claim against income taxes later on.
I am required to have a degree to earn money
Not really true. You are required to have a degree to have a particular job of your choice. It’s up to your government to decide if having that choice is something it wants to encourage, with income tax breaks equivalent to the cost of tuition (the loan principle) or if that is a luxury that is taxed like any other luxury.
The interest on loans is not a tax. It’s the expense of accessing capital immediatly. Again, it’s up to your government to decide if accessing capital immediatly is a necessity eligible for tax breaks, or a luxury that comes out of your after tax income.
Also don’t forget consumption tax which may or may not apply (usually not on loan interest).
