The per vote subsidy ossifies the political system. It undermines  the rise of new political parties that might have more support than current parties,  favours current regional parties, and, in the case of Canada, has subsidized separatism. The per vote subsidy entrenched the separatist Bloc Quebecois in the House of Commons and eliminating  it coincides with its decline. Low political donation limits , possibly even lower than they are now, together with  high tax deductions for those and strong limitations on third party spending,  controls special interest domination.
