Don't do it, man! You'll have a hard time finding a good (read interesting) job without a PhD and with a PhD, you'll be out of work at 50. And you'll be bitter. Oh, and that PhD needs to be from a top ten university and you need to work for a big name and you'll have to work a lot harder than you think unless you're real smart. Oh, you'll also have to do a post-doc at an even better university and with an even more famous professor. If you're real smart and lucky you can make six-figures. Maybe, till you turn 50. Then you have to find something else to do. Or maybe you can get an academic job and you'll have to work 80 hours/week for 5 to 7 years after that post-doc till you get tenure, if you do. If you don't then you start over. And you may never make six-figures.
It's a lot harder to be a happy chemist these days.
