It was once quite common for people to work completely unglamorous assembly line jobs for decades at the same company. Maybe the real issue is that google's hiring practice selected for prima donnas?
Maybe the smart people saw what happened to those that chose to work unglamorous assembly line jobs for decades and realized it's not to their benefit.
Probably because they want actual raises over time instead of the promises of increasing pension pay, which as have many found out is just a lie. Even big companies like GM, promised good pensions years ago, hit a double and got rapid inflation to make the pension payments a fraction of what they were expected to cost, then decided it wasn't enough and went for a triple by successfully lowering pensions for people that have already long retired, bought out other's pension plans for similar pennies on the dollar caused by the fear of lowering pension payouts, and then gave bonuses to all of upper management afterwards because they did so good at destroying other people's retirement and possibly life.
