Plenty of people 'contribute' without earning income. For a long time that was the norm in this country; men generally earned wages while women stayed at home, raised children and took care of the house. While that is not the norm it once was, there are still probably millions of housewives and househusbands out there who earn no income and would have less of a voice under a tax based system.
No they file joint tax returns so the stay-at-home housewife gets the same number of votes as her husband.
Your argument seems to boil down to the same basics as the 'only federal income tax payers should get to vote' proponents...
No because Williams' argument is that everyone gets a vote. You still have a sizable portion who don't pay taxes who would still have political influence.
If the top earners would only have one extra vote, what is the point? It seems to be to limit the voting rights of those that you (or Williams) deem less worthy. It is the idea that income determines worth again.
No that's your characterization and it's based on a false premise. This has nothing to do with your worth. Again, do you give half your check to a homeless person to keep them from feeling less worthy? I doubt it.... you'd not be in favor of such a thing. Nor would you allow the homeless person to dictate how your money is spent. Has nothing to do with how much worth you think that person has.
No one has said a damn thing about limiting voting rights, again, that is you interjecting a characterization that is false. Again, your votes would be proportional to the amount of tax you pay and there is nothing unfair about that... we do this all the time... you go to a hotel and you can pay the economy rate and get the bare essentials or you can opt to rent the luxury suite. You rent a car, you can pay a little and get an economy car or pay a lot and get a luxury car. It has ZERO to do with what you are worth. If you paid for an economy car then demanded to be given a luxury car the rental agent would just laugh at you. It's not because he doesn't think you're worthy.
Once again you have this need to equate government to business. They are not the same, no matter how often you use such comparisons. Yes, government uses money, but it is not a business.
Worth is absolutely part of this type of system. What is each person's political opinion worth? That would be determined by the amount of taxes they paid. If a person gets 2 votes because of their taxes and another person gets 1 vote, the first person's opinion, their political voice, is stronger, is worth more, than the second person's. If some people get more votes than other people, the voting rights of those other people are limited. By expanding the voting rights of some, the voting rights of others are inherently limited.
The basis of this idea is that money determines how much a person's voice counts in our political process. That is already an unfortunate reality, I don't want to make it even more prevalent.
