I don't disagree, but the high-waisted era works a lot better for girls with more curve to their figures, which I see as a net gain.

And considering the number of overweight/obese people continues to grow apace, it's not a bad thing for them to be able to feel good about themselves and have fashion options that flatter their figures instead of all fashion being catered to near-impossible body types.

This should not be read as an endorsement of obesity, which can be a dangerous medical issue, but rather a willingness to see that everyone deserves to feel positive about their self image. Weight gain is a difficult issue to tackle in a country that subsidizes corn syrup and puts it in damn everything, on top of a broken education system that certainly doesn't teach people healthy eating.
