Ehhhh... I don't know that capitalism can be blamed for personal irresponsibility. I'd say it's more of a motivation / knowledge thing. You don't have to live in the gym to get in shape. I spend about 4.5 hours per week total. Even when I've been in the very rare 70-80 hour/week death march, I could take an hour out of my day to go to the gym and lift.
Similarly, dieting is not an activity, more so the absence of one (shoving food in your mouth). When I'm cutting weight, I have more time because I'm not cooking eating food all the damn time. Eat a carrot rather than a Pizza to lose weight is not super rare knowledge. It IS uncomfortable, though.
Okay. And now add any of the following, or a combination, to that situation:
* Ill partner or family members to take care of
* Child(ren)
* Studying
* Long travel times
* Irregular working times
* Poor upbringing food wise
* Stress
* Sleep deprivation
* etc
Is it still so easy then? That pizza tastes good and is real comforting.
