Haha, yeah I can see why it would sound like that if you haven't experienced similar issues. I would disagree on 99% of people not having tongue posture issues though. If you look at the structure of a lot of modern people's faces, we have an "adenoid" face - narrow, long midface, lack of pronounced cheekbones and eye support. The hypothesis is that chewing is an essential part of proper jaw development, and modern soft diets don't make us do enough of it.
