I have a really hard time billing more than about 30/week without feeling like i'm being taken advantage of in those situations. There are all kinds of non-billable activities that you do as an agency developer that need to be accounted for; hitting 40 billable hours means I did 50+ actual hours, minimum; oftentimes more. I went out on my own again after a couple of W2 jobs and this time resolved to calibrate everything on the assumption of working 20 hours a week, including my rate. End result: I'm not overworked (not on my client work, anyway), I don't feel stressed about making my quota, and I have more money coming in than I ever did as an agency dev. I will probably take another W2 job at some point but after burning myself out several times on my own startup, compared to how I feel about my client work (nice and rosy feeling) I feel pretty confident that I won't let myself get pushed into it from an employer again.
