It's probably got more to do with choice. If those TED talks are to be believed, then choice is bad for mental health. If you are wealthy or live in a wealthy country then you have lots of choice. It's somewhat ironic because politicians that operate within wealthy countries will often emphasize choice as a reason for privatising public services etc.
The paradox of choice is not very robust in practice. The experiments are often difficult to replicate and small variations in experiment design make the paradox of choice vanish.
The problem with choice is that even knowing that it's bad for mental health, that doesn't translate into a moral prerogative to forcefully limit the choice of other people.
But yeah, choice, and its cousin perspective: If a bad day involves not eating or your brother dying from preventable disease, it's not hard to see how a meal every day of the week and good health can translate into happiness.
