Fares on the city-run public buses in Greenville are subsidized by city tax revenues, but among the beneficiaries of the low fares are many people who commute from outside the city to jobs in Greenville. Some city councillors argue that city taxes should be used primarily to benefit the people who pay them, and ttherefore that bus fares should be raised enough to cover the cost of the service. Each of the following, if true, would weaken the argument advanced by the city councilors EXCEPT: ['Increasing transit fares would disadvantage those residents of the city whose low incomes make them exempt from city taxes, and all city councilors agree that these residents should be able to take advantage of city-run services.', 'People who work in Greenville and earn wages above the nationally mandated minimum all pay the city wage tax of 5 percent.', 'Voters in the city, many of whom benefit from the low transit fares, are strongly opposed to increasing local taxes.', "Many businesses whose presence in the city is beneficial to the city's taxpayers would relocate outside the city if public-transit fares were more expensive."]
