I worked full time during undergrad, and both post-graduate degrees, Also had a family and small children. It can be done.
One of the major reasons college costs are so high is because someone else is paying for it. Freshmen students don't comprehend what kind of debt they're taking on, but they are lulled into the idea that it will come due later, and they can go to school and party now, and pay later.
Then when their student loans come due, they march in protests demanding that they all be forgiven.
If you want an education, you can get one. It shouldn't be handed to you. It's not my duty to fund someone else's education involuntarily. There are scholarship funds I'll donate to, and other ways to help. We don't need government funding everyone's post-high school education.
