While most people disagrees but my experience was different. I used to work with a US firm years ago and my hourly rate was $12 however our company charged $80 to $120/hr to our clients. This is how offshore companies operates...
Not just offshore. I once worked as an employee at a company that was paying me $60k/year (which works out to roughly $30/hr), and billing me out at $250/hr. There was a lot of pressure to work billable overtime, too, and as salaried employees we didn't get paid for it.
