Commercial real estate is pretty cheap in most of the country, we have 3 shifts in my building and are open almost 6 days a week, sharing desks with another shift, my company isn't paying thousands of dollars per person per year for this building.
Not every place is the bay area with insanely expensive rent and insanely expensive cost of living.
I've still seen exactly no one even attempt to explain to me why a payroll company needed to raise 200 million dollars.
