This sentiment is pretty popular amongst some of the younger working people... they work, pay a lot of taxes for everything, and then get outvoted by pensioners who retired under "old" laws and now get a higher pension than they ever earned while working (i'm talking from a position of government pensions, not the american save-for-yourself style). So, old people vote and decide, and young people get the bill for that.

The "if you contribute more, your vote should be worth more" sentiment would change a lot, because many actually rich people don't really pay a lot of taxes compared to higher middle class (engineers, doctors,..). If your vote was worth eg "log10(your-income-taxes + 1)" (to make buying a lot of votes impossible), more power would go to higher educated and higher paid people and less to people who don't contribute to society (at least not financially). Again, i'm talking about a society where pretty much everyone who works also pays income tax, and you're not cutting out the majority of poor people.

Would it work? Probably not, but i understand the sentiment.
