” As Moshe from Midwood noted, Congress is unlikely to legislate around the inconveniences incurred by a minority of yidden just as they no longer are captive to the views on this subject held by a few thousand Dairy Farmers whose cows don’t hold by DST.”
These aren’t the only groups that oppose it. The National Association of Convenience Stores, for one, opposes it. Educators from around the country are concerned about kids going to school in early morning darkness. Health experts believe that standard time is better for keeping a healthier sleep cycle. I am not saying that there are no benefits for permanent DST but there are a lot of concerns as well.
Also note that this was tried in 1974-1975 and was greeted with strong backlash.
