Liberals would never voluntarily pay more to the government because most of them can't even afford it anyway
Its no surprise that most people who want more services are people who pay the least taxes, have the least income and would continue to do so
More busses in the area, more security, more healthcare, pooled income, shared business -- they can all be accomplished right now privately by a group of people -- but the people who want them most wouldn't have enough money to cover it , hence why they want socialism on a national scale
