I have this client that pays me very well for working on a project that is clearly doomed. I tried to communicate my concerns in the most positive way I could, but he is unable to see the writing on the wall. I can't do more without sounding like a Negative Nancy.
He is filthy rich and is more than capable of paying for any failure, but yet I feel bad about the money he is wasting on me. Sometimes I consider leaving the project, but I'm unsure about the benefits: client will just hire another guy and I would lose 150k/year income.
I reached a point in my career where I'm cynical enough to not be burned out, but my moral compass is tingling. Any advice?
