So you're saying the current tax system for schools is equitable.   Have you compared inner city or poor rural area schools with for example Bellevue school district?

Regarding your Robin Hood comnent - that reflects how ignorant you are about the USA.   This country is owned and paid for by the rich.  Don't believe me?  Check where federal tax dollars come from.  The rich in Washington state live in a tax haven and those days need to come to an end.
