Tuition fees in colleges shouldn't be replaced with a graduate tax because it's not fair to tax the individuals that are proactive enough to acquire an education. With that in mind, the government can't levy such a tax because it would be struck down by the courts as unconstitutional at its core.
I do not believe there is any reason for tuition fees to be replaced by a graduate tax levied by the government. I would say this because our current tax system is already a mess of jumbled rules and laws and it is terribly inefficient. Secondly, it wouldn't benefit anyone for the government to take on the additional work of collecting a new tax.
Tuition fees should not be replaced by a graduate tax levied by the government. The government should stay out of the profit making by issuing another new tax upon colleges and universities. In this economy, the government should be giving back to everyone and not trying to line their pocket books.
No one should be taxed for getting an education. Although student debt is a massive problem facing many students today, taxing one's college education isn't the way to go. If governments rely on this revenue for operating budgets, what happens when fewer people go to college? Revenue goes down and services are cut back when there is less money coming in. Plus, that's not how a consumer-based society works when someone pays for using something years later. I can't go to Wal-Mart and say just tax me for these groceries 10 years from now as a form of payment.
Tuition should not be replaced by a tax. People who do not attend college would not agree to pay a tax that does not benefit them. Also, people who go to college do not have a problem with paying tuition since they get to take advantage of the benefits of their education.
