Now this is what I call tall-shaming... Just kidding. It's just stupid and probably self-affirmation. Maybe, just maybe, if you want to save on food, especially talking about the US (or the EU), then it would be easier to stop overeating as the US is a pretty obese society. Obesity mostly comes from all the calories people don't need, so could easily not eat. Without shrinking themselves along the vertical axes. BTW, maybe being tall means a shorter lifespan on average, but so does being obese.

And then we haven't talked about all the food that gets discarded.

After all this the usual mumbo-jumbo about tallness being somehow magically a capitalist sin is not that surprising. Though, of course, it has nothing to do with it. Being tall has been seen as favourable/attractive by women for a long-long time. It's evolutionary. Maybe it doesn't make sense, but boobs don't make sense either. Neither does love, for that matter. I mean in our current day and age.

If capitalism favours the tall, that's because people do favour them - to some extent. (Yes, men also associate positive traits with tall people.) Maybe we can try to do away with some of the illogical associations (like tall people being seen as more competent AND more competent people being seen as taller), because these may cause problems. Just like we do with other evolutionary coded prejudices. But coming up with nonsense/non-actionable fantasies about how we could make the population shorter is stupid.

And not helping your children if there is a safe and efficient treatment is evil. I'm 6'3". I know that it doesn't automatically make you attractive. But I also do know that women are mostly attracted to guys who are taller than them and who are taller than the average guy. Now everybody can't be taller than the average but handicapping your children is pretty nasty. (Unless, there is an inherent risk to the treatment, which I don't know, but it seems that the author doesn't care about it either.)
