If you want to be a doctor or lawyer go for it.
Is it necessary? Not at all.
I started a sales job the day after I graduated from high school and never looked back.
Most newborn babies are far wealthier than college graduates. Sounds crazy I know but at least they are starting at $0 and not (-$100,000).
You don't need college to learn how to log onto bigger pockets and learn investing and wealth creation.
Hard work to create income (hard work seems to be a lost art these days) , dedication to live within your means, grow your sources of income, invest what you save into cash producing assets, grow those assets... repeat. No college is necessary to wrap your head around that process.
I always say, try living in the real world a few years giving it all you got before deciding on that expense. For $100k worth of loans you can do a decent SFR in parts of the country producing $250 cashflow a month. Watch what that investment does in 10 years.
