We are witnessing the effects of what happens when those that do not pay taxes are allowed to vote. Those that do not pay taxes are currently electing the people that spend taxpayer money. Only taxpayers should be able to decide who should spend our tax dollars.
If our current system remains, those that pay no taxes will continue to elect politicians that promise them more handouts and benefits. thereby creating a larger welfare state, which would create more non-taxpayers.
We have witnessed many nations implode under the weight of ever increasing social welfare and debt, produced when non-taxpayers have a say in where other people's money is spent.
