True, no one's pointing a gun at them and telling them to buy the packs of raman rather than the 5lbs of carrots, but there are forces in play (market forces making it cheap to get a whole meal, time forces making it faster to prepare and eat the meal). It would be great to have an insurance company with an economic incentive working for these people to give them healthier alternatives.
I wouldn't call Switzerland's laws "lax" - there are lots of guns, but you won't see the American style gun toters that want to bring their handguns into the bar (hard to get a carry permit
without a good reason there). The thing with the European solutions is many of them have health care that's cheaper overall - not just for the individuals, but the total healthcare spending per person is lower than in the US
, including private and public costs.
