Kevin works hard as a banker. he makes a good living and has a nice house and car. he believes that everyone should have to pay for his or her own higher education, and if that can't be done, the person shouldn't be able to earn a diploma. which theory aligns with kevin's views on inequality due to capitalism

The theory which supports Kevin's view is known as liberalism or neoliberalism, and defends individual freedom, the fight for the own interest and economies which are independent of the interventions of governments. This in turn, would bring the best possible outcome for the colective as public spending and state intervention distort markets, which allocate resources and income more efficiently on their own.

Connecting (neo)liberalism with Kevin's views, people who cannot pay their higher education would not be able to study, as he supports the idea that public spending thorugh scholarships or cheap loans should not be granted to people without means to pay their studies . In turn, they should find their own way within the markets system, for example, find a job and earn the money, obtain a private loan and return the money afterwards, etc.

what are the choices? the multiple choices?

i will answer in the comments after the choices have been said.
