I have some questions about these sentences.
We are a culture more sexualized than ever (Mad Men notwithstanding), with technology that’s made it easier than ever to “better” ourselves, warping our standards for what’s normal. Plastic surgery used to be for the rich and famous; today we’ve leveled the playing field with cheap boob jobs, tummy tucks, and outpatient procedures you can get on your lunch break. Where that leads us is running to stand still: taught that good looks are no longer a gift but a ceaseless pursuit. （from a Newsweek article)
What does “running to stand still” mean in this context? And what is “taught” grammatically?
