why does daylight savings still exist in the United States?
In the United States, the economy used to be heavily based on agriculture.  Therefore, daylight savings was originally instituted to facilitate a farmer's workday so that much of the working hours could coincide with the hours where there was more daylight (daylight begins is later in the spring). Since then; however, the U.S. economy has become less agriculturally based and also with technological advancements that have drastically impacted American work patterns, the need to follow daylight windows has reduced dramatically. While daylight savings still allows many Americans to spend their working hours during the daylight, there is the popular opinion that daylight savings should no longer be observed in the United States, especially with the confusion that comes with changing hours during the spring and fall.  There are at least a couple states that do not change times for daylight savings which further adds to the confusion.
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
