Expensive cities are killing creativity

Al Jazeera wants you to move to St. Louis.

As someone living in New York, my most common response to these sorts of article is:

1: Okay, but I can't just pick up and go to some artist's utopia. I have a job and (hopefully) a career to think about. I made the decision to move to New York years ago and now for better or worse I'm here, and working in a job that is not super common elsewhere.

2: Okay, New York Sucks (Big Cities Suck), so where should we go? Portland, OR where there are no jobs? Austin, same? St. Louis, apparently?

3 (Bonus/most confusing): If you work in tech, are just starting out in your career, where is the intersection of a city with robust tech scene to provide you jobs, and yet low rent and thriving art scene?
