A single semester of college tuition, even at a state school, routinely runs into the thousands of dollars before books, housing, or anything else gets added. That's the real, upfront cost of pursuing the traditional path toward a future career, and it's a legitimate, serious number.

Building and testing an app idea costs almost nothing by comparison. Describing an idea in plain English and getting a working version back requires an afternoon and, depending on the tool, a monthly cost that's a small fraction of a single textbook. Not thousands of dollars to find out if an idea has potential. Barely anything at all.

This isn't an argument against college for the people who genuinely need what it offers. It's a reason to notice that testing a business idea no longer carries anything close to the financial risk that pursuing almost any other path does. You can find out if an idea works for less than the cost of one class, before ever deciding what else you want to invest real money and years into.

The gap between these two numbers is enormous, and most people never stop to actually compare them side by side.
