You're talking about your marginal rate and we simply are far to the left on the laffer curve, raising taxes will raise revenue. I'm not unsympathetic, my marginal is close to the same - but generally I think people's claims that they will stop working are generally more bark than bite and the evidence largely backs that up.
If you don't want a tax-based solution, I do hope you are agitating for SS and medicare cuts.
