it's more then poor people who don't pay taxes. The current tax system hinders people from being able to make additional strides towards their goals now since there is only so much time available in order to sustain out of control government spending/political programs which are used to buy votes. If overall taxes were at 15-20%, people would be able to pay off homes faster, invest more, and have more collateral to start businesses....which would possibly lead to the same taxes being collected since more is technically being spent and would create long term sustainable revenue. Cities have used the same strategy to attract large corporations and ultimately leads to more jobs, tax revenue, and start up ventures from people being successful
