Effects on circadian rhythm are severe and can last for weeks.The government of Kazakhstan cited health complications due to clock shifts as a primary reason for abolishing DST in 2005.There. Health and money. If you don't care about one you're likely to care about the other.
Clock shifts correlate with decreased economic efficiency. In 2000 the daylight-saving effect implied an estimated one-day loss of $31 billion on U.S. stock exchanges. Clock shifts and DST rule changes have a direct economic cost, since they entail extra work to support remote meetings, computer applications and the like. For example, a 2007 North American rule change cost an estimated $500 million to $1 billion. ~~Wikipedia

Please, bear with me...
