However, there are a number of arguments in favour of making university education free for all. Firstly, it will encourage more people to attend and this will benefit society. This is because it will lead to a more productive and educated workforce. Research has generally shown that those countries that have a better educated population via university have higher levels of innovation and productivity. In addition, there is the issue of equality of opportunity. If all students are required to pay, those on a low income may be dissuaded from attending, thus making it unfair. The reason for this is that they will likely not be able to secure financial support from their family so they will be concerned about the debts they will incur in the future.
