1. Just because the majority voted for something that does not make it right. To give an admittedly extreme example, the majority in Germany voted to despoil and later kill Jews.When NYS enacted rent control, while not all agreed with him, Rav Hutner termed it gezel baal habayit.
2.While as in other monetary matters minhag mevatel halacha, the preferred method is to tax according to the benefit. If all benefit equally the activity is financed by a head tax. If the rich nbenefit more than the poor by wealth taxes. If the benefit is mixed the activity is financed half by the former and half by the latter (see, for example, Shulchan Aruch and Rema Choshen Mishpat 163:3).
3. The government in enjoined not to overtax (Nehemia 5:15, Midrash HaGadol Shemot 21 Introduction to parasha, Ple Yoetz “tikkun”, Rav S.R. Hirsch “Horev” 95:604). What can be done by civil society should not be done by government and what can be done by a more local government, which is closer to the problem, should not be done by a more central government. For example, monetary disputes can be adjudicated by “judicial companies” (e.g batel din) but except for certain groups social pressure is insufficient and government enforcement is necessary – but not necessarily at the Federal level.In fact, alternative dispute resolution (ADR) is gaining popularity due to the expense and time-consuming nature of suits in government courts with many contracts containg ADR clauses.
