I'd sign for it. Just imagine: millions of people that can't switch providers that you can charge whatever you want. Coupled with a legal system that provides a steady inflow of new consumers. It's a super business model (albeit totally un-ethical). Most businesses are happy with 30% gross, that seems to be the number that normal and healthy businesses strive for. Plenty are happy with 20%. 50% is on the very high side of gross margins. Sure there are a few outliers but it definitely isn't normal.
