Interesting, the response in the UK has been to address this by attempting to pump money into programmes to to try and prevent type 2 diabetes or at least reduce its growth. Still too early to see how these efforts will be.
Anecdotal but a 50ish year old friend had Type2 and went to stay with relatives on a farm for a few months. He spent 10-12 hours a day helping out and when he came back he'd lost weight and also was no longer diabetic.
Interestingly, the other thing that's a risk factor is lack of sleep. Huge commutes put you at risk for type-2 diabetes. Who'd have thought?
