There's a lot to unpack here.
In my opinion (and observation), the majority of the population worldwide wants a boat. Whether it's attainable or socially acceptable depends on where you live. In America it is attainable and mostly socially acceptable. You can't fault people for grabbing their dream when it's within reach. Most immigrants want to move to the US because they can "buy a boat". It's literally the point.
People really really love meat. They don't need much persuasion to resist any message that says what they love is bad. Like, people love meat so much that it's probably something our bodies want and need over other forms of sustenance.
I'm not sure why so many people think that there's an effective brainwashing campaign behind all of this. I think it's just what individual, free thinking people want.
> It has to do with the American exceptionalism thinking. That Americans are special and therefore more entitled to over consume.
This is quite a leap, and you're giving people too much credit for "consumption as a guiding principle".
Most people just have extra income and are bombarded with messages about how something will make their lives better. They try it out. They're stuck with it.
