"...critics of private governments claim that HOAs erode support for public institutions. Those who join can bypass the public system: homeowners who fear crime do not have to vote for tax dollars to attack the root of the problem; they can build a gate to keep the criminals out. Opponents maintain that the erosion of public support, reflected at the ballot box, leads to further deterioration of municipal services and reductions in local revenues. Nonmembers experience a reduction in public service levels and may be worse off. At the extreme, homeowners associations may contribute to sentiments of secession and withdrawal from the public sector."
