Because those people are now getting additional votes that affect an area in which they do not live. If I'm a business owner and just need employees with minimal education, what is my incentive to increase taxes to pay for education? At least if I lived there an argument could be made that my family or neighborhood would be affected. Who's voting to increase minimum wage, or engage in conservation and beautification? Not the businesses. Having more money (to start a business or have investment properties) should not equal more votes. It already equals larger sway on elections. Why not just cut to the chase and have an out and out oligarchy?

The article itself mentions that there are almost as many businesses as there are people voting. This will not result in elections being the "will of the people."
