Why is GOOGL cheaper than GOOG?

2,044.36 (GOOG) vs 2,026.21 (GOOGL)

It's been like this for almost a year for no reason whatsoever that I can find.

GOOGL should be worth more than GOOG because it offers voting rights in addition to the exact equity as GOOG, yet the market is saying the opposite.
