An income based tuition policy similar to the progressive income tax system would make college more affordable. Students would pay varying amounts on college tuition depending on which income bracket their family falls into. Although many schools currently take a student's income into account, often times, the aid is inadequate.
Free applications would remove an obstacle that prevents low-income students from even applying to school. This is a policy that many schools have already instituted and have seen encouraging signs of a more economically diverse applicant pool.
Some have proposed material costs being included in tuition. Textbook costs are one reason the price of education is so high. This alleviates one portion of that price.
Money that you put away in a 529 account is used exclusively for education and is left to grow tax-free. Plans are very flexible and can accommodate many different financial situations. These accounts are a great way to save up for school costs.
