I have taken classes online and in person, from 4-year universities and community colleges, and without question, online university degrees should not be allowed. Some courses, like math courses, you don't need interaction with others to learn, so that's fine, but courses like biology (with "virtual" labs) or English where you should be discussing with others, are useless online. It's also a LOT easier to cheat.
Almost everyone in America has Internet access, whether through a computer or smart phone. Getting an online degree from an accredited brick-and-mortar institute of higher learning is a cost-effective way to earn an education for working parents. Online university degrees are unique ways to earn training credits for advanced degrees so parents can make more money. There is no room and board and hardly any residency requirements. Online degrees cost less which prevents economic burdens on families and on student loan companies.
