Maybe the landscape has changed a lot, but when I was a consultant working at client site way back when, I was getting paid $40/hour, while client was billing $65. There was no 401k matching, health benefit, or vacation though. It was W2 in name only. The only thing the consulting company did was to find my resume online and send me to client site for interview.
