If you take that approach, then you need to weigh the good and bad that the government does and how it does it's allocation. If it has more money will it go to war more? If it has less money will it cut social programs or cut down on military adventurism? If it has more money will it be directed to special interests since social programs are already funded at a good level -- does more money enable corruption? I agree with you about earning more money being for altruism; I think it's better to work a week and donate the money than do something you aren't skilled at. e.g. building houses when you can program and pay for 3 skilled builders - more gets done and at a better quality.
