"We" don't change anything if people want to shoot themselves in the foot. The only thing you can do is lead by example. For those commuting ~100 miles/day the difference in annual commute cost between current prices and previous high prices considering driving a 25 MPG vehicle is about $1800. Presumably the job is worth that (or more) between work environment and compensation. It may not be worth the extra time and money to you, but it clearly is to the person doing it, so there is nothing that needs to be changed.
While personally I don't view a 100+ mile commute as desirable I would absolutely do it for the right amount of money. When I consider a new job I have always crunched the numbers on job related expenses. That includes gas, tolls, public transit and additional taxes if applicable along with a subjective weight to the type of commute. If the work and environment seems good I weigh any additional expenses against the pay increase. It's pretty simple, and I'm sure everyone figures out the costs at least approximately to determine if it's a worthwhile opportunity. Others may do a 100 miles commute temporarily and plan to eventually move closer if it turns out to be good long term thing, or find something else if not. I did 150+ miles a day for months when gas prices were high. I didn't mind and the net pay after commute was better than what I could find locally. It was not something I'd have done for years though.
