Be ready for a shock.
In order to illustrate the growth in college costs between our time in college and today, imagine if the minimum wage had grown as much as public college costs between the early 90s and today: basic minimum wage woukd be $50 an hour.
Once you’ve recovered from the shock, start plotting how you can finance college (lots of good advice on this website).
