TBH I just see it as false platitudes since there's it's very likely the burger I'm eating wasn't some ethically raised and slaughtered cow. Sure, I didn't do it, so clearly I'm absolved of all fault there.
When I have the option of choosing meat from a cow raised and slaughtered ethically I'll take that one every time, but usually I have no idea of the provenance of a particular hamburger patty and that likely does wonders for my peace of mind.
Kobe and Wagyu beef are raised happily and slaughtered ethically in order to be the quality that they are, in theory.
I believe economics certainly plays a role here.
A pound of Wagyu Chuck costs $160 at a nearby grocery store but I can get Prime Chuck from the local big chain grocery store for just $12 (a 13x price difference).
I find most "happy" beef is nothing more than an illusion for lazy rich people to pretend they're not doing a bad thing, but why not AT THE LEAST choose to eat that or not eat meat?
