Care to share these moral reasons?
What I am saying is that you should consider that maybe these people are not innumerate - they could realise that the policies they are voting for will harm them but they believe that it is the correct thing to do.
Some people think that federal taxation in general is morally wrong and should be reduced. Whether you or I agree with that is irrelevant if what we're debating is have these people realised that it could help them but still think it's right to vote against it.
How are any of us supposed to vote in our best intetersts, individually or collectively, when all the bastard politicians are pathological liers.
Read history, read the news, read foreign news sources (since they have less of an incentive to lie to you about your own country's domestic policies), use your brain.
View through all the lenses at your disposal (there are many), apply critical thought and compare theory to fact. If you find your answers change from absolutes to 'it depends which perspective you start from' then you are probably on the right track.
Many people realize that such legislation would benefit them, but don't feel justified in depriving another individual of their property.
That is, me and many others don't view taxation as theft but as a charge for providing an ideal environment to amass wealth.
As stated elsewhere in this thread, it's not about "the right answer". It's about how individuals often act according to their moral view of the world. Just because you don't share that view, doesn't make their conclusions automatically uninformed and incorrect.
