I think the OP is providing value, just at a rate which can't be calculated using 19th century industrial era compensation schedules, i.e. the 8-hour work day. OK, it actually became shorter than before, but the main point is that software is not the same as machining shoes.

There's a difference between how effective the OP is at being a team player/contributor, and a worm who tries climbing the social ladder with as little risk to his/her self which I believe you allude to. It seems to me the OP is not the ambitious type and found his place in the industrial matrix.
