The perk also includes: 10 years of salary to your spouse, and monies also for your children. Googlers typically aren't going to microptimize expenses this small.
I think this is the real perk -- I remember in ~2008 that sadly, a googler's family had to take advantage of this when they passed. It stood out as the company really taking care of the team. I have no clue if they still do this today but it was certainly a wow moment.
back when google was great, my manager had to call a coworker's parents, who lived in Iran, and explain that their son had been badly injured in a parachute accident and was in the hospital, but that Google would be paying all his bills and we'd do the best to get him back on teh ground so he could eventually return to the office. (said employee left right after to be a VP at a bank. I thought that was a jerk move).
