In my opinion, the cons of DST don't offset the pros and its still beneficial to change the clock back in the spring. I think, the disadvantages of Daylight-Saving Time do not cancel out the benefits on below given grounds:
• It is helpful to save the energy.
• It gives extra time to stay outside.
• The roads are brighter during the rush-hour in the afternoon.

In fact, its a myth that DST was intended for farmers. Farmers always go with the daylight instead of clock but anyhow farmers get extra time to spend in the farms to get more benefits from the daylight. In my point of view, DST does not affect the Muslims during the month of Ramadan, because Muslims go with the sunrise and sunset regarding fasting. Sunrise and sunset does not affect the fasting durations, indeed.

I think global economy will weaken if every country quit using DST. Because of DST countries can conserve energy otherwise it will become a huge amount of power will go into waste. The world travelers will spend more money in the visiting countries and which will help to support the economy of the country. The tourist will have more time to have fun during their vacations.
