Time... aren't exactly being truthful. They constantly refer to "take-home", rather than pre-tax. The all in cost for a person includes desks, computers, managers, electricity, office space and so on. Common sense suggests they are likely making 30% or so margins. If it were much more than that a competitor would eat their lunch. Look at the publicly listed services companies like DXC, Wipro, Accenture - margins are 20-30%.
