But if you go permanent on no DST, it’ll be too dark at the end of the day year round.
Sure, you won't have daylight at 10:00 PM at night, but honestly, who needs that? Businesses can exist with or without daylight that far into the evening hours.
The bigger issue is ensuring that kids have daylight in the morning hours when they're at bus stops heading to school, and for those who have physical, mental or psychological conditions that are made worse by changing the clocks. That's primarily why full time DST was abandoned back in the 1970's when it first attempted.
