You can look at these kind of foods like illegal drugs. Not biggie in moderation but if you overdo it then here come serious health problems.

I'm 100% convinced that people who are morbidly obese not getting a second serving or not getting those extra nuggets is as hard as a drug addict not picking up a needle or straw or a lighter. You fucked up.

EDIT take the cost on society and obesity must be more expensive than that of all drugs combined. Something like half of the US now ?

I wonder if they go at it from that angle ("let's make these kids addicts for money!"), or if they gaslit themselves into something else. It's probably the latter, just like the tech companies did - they looked at just the numbers and analytics, did some tests, saw that if they do X then numbers Y and Z go up, rinse and repeat across decades.

This is why Google no longer has just some unobtrusive text ads to the side. At the time it was great because it wasn't annoying, but then the analytics came in and showed that more prominent and better camouflaged ads had higher conversion and revenue. And people grumbling aside, their revenue multiplied over and over again.
