Permanent-DST is confused people thinking DST is cool.
Money is driving this, not coolness. Owners of convenience stores, tourist attractions, and similar businesses profit more if we all get up earlier in the day, and they spend way more money to lobby the legislature about timekeeping than the rest of us do. The costs of getting up earlier (for example, it increases cancer rates) are not nearly as well known or measured and hardly anybody lobbies the legislature against daylight saving time. Speaking of cancer, remember that study I mentioned in November that reported that breast cancer rates in the US are 12% higher in the western parts of time zones, where people get up earlier in the solar day? In April, Harvard researchers published a similar study about liver cancer, and found an effect there too: they reported that moving west within a US time zone significantly increases the incidence of liver cancer.
