The strongest argument against college is an unmanageable amount of debt, which can haunt you for decades, and I have many friends who suffer from this.
The strongest argument for college is the connections you can make which will be with you for life. I know countless people who can trace their career opportunities back to people they met in college, whether or not they even graduated.
Both factors can be overcome. You can pay off your debt diligently, or attend a school that is so cheap this is a non-issue. You can make connections other ways. But you will pay a price one way or another.
In my opinion those two things are the fundamental factors that determine whether or not going to college is a good idea, and should be the main considerations that help you decide whether or not to go. Every other aspect of this discussion seems like a giant red herring.
