Wording a question like that is so... biased. Maybe we should work on fixing how the enormous amount of tax money is spent now before asking taxpayers for more? $700bn in funding for military (around $1tn all funds considered), yet there's "increasing inequality". US spends 2x the amount the UK does on health per capita, yet the UK can afford single payer health. Administration costs are through the roof.
I think this is a case where "throwing more money at the problem" isn't the right solution.
