I don't see why you're blaming Google for you feeling demeaned. You had the option of trying the FTE route instead of the contractor route, if you wanted to be a full-perk Google employee. Maybe you didn't realize going in how you'd be partitioned from the FTEs in all their daily benefits, but that's not their fault.

TVCs jobs have strictly-defined boundaries, and anyone who feels personally offended by that, shouldn't be in those roles. Your comment is a fair warning to anyone who's thinking of going that route.
