Sure, become a plumber if that's something you're passionate about, but in the 21st century, we're not cogs in the machine.
President Obama may have the goal of America having the highest proportion of college graduates in the world by 2020, but in New York City, that idea's sprung a leak. According to Mayor Michael Bloomberg if you're not at the top of your class you should probably forego higher education in favor of becoming a plumber. Indeed, the New York Daily News reports that last Friday on his radio show Bloomberg added fuel to the "Is a college degree worth it?" debate by saying that for the average student, becoming a plumber makes more financial sense than going to college.
A plumber doesn't waste "four years spending $40,000, $50,000 in tuition without earning income," said Bloomberg. They also don't leave school with tens of thousands of dollars of debt and can make a pretty good living while they're on the job. Added bonus: your job as a plumber (or car mechanic, or electrician) can't be outsourced.
