This sounds very similar to Milton Friedman’s voucher system. The reason for a voucher system is because school funding relies on property taxes for about 80% of public school budgets. The problem is that property taxes don’t fit either the Ability to Pay or Benefits Received principles of taxation. Your neighbor may pay the same amount of property tax for their house but have 4x the income, which violates the Ability to Pay principle. Likewise, many people do not have children currently in school and a lot of people have never had children at all, which fails the Benefits Received principle.
The voucher system removes some of the objections to the property tax, especially if tax payers with no children are allowed to sell their voucher on the open market. It does not appear that the GA proposal allows this.
“Your neighbor may pay the same amount of property tax for their house but have 4x the income, which violates the Ability to Pay principle.”
“Ability to Pay principle” - first I’ve heard of that ‘principle’, might you have a link to it?
In the country where I grew up, the capability to access what you wanted was based on how much money you earned.
