Google treats you well*!
*if you're willing to toe the party line and not advocate for workers' rights, not fight against surveillance or military uses of their products, white supremacist hiring practices, and caste discrimination.
But other than that, sure.
Let me answer this for y'all.
Because Google treats its employees well and values us as complete human beings, and smart people want to be treated well.
It's not the only place that treats employees well, but some startup CEOs are vocally disdainful of their own employees.
