There is a lot of evidence that points to the fact that money does not always mean a better education. Some districts in the US spend up to $16,000 per pupil and are still rated unsatisfactory, while others spend as little as $4,500 and are rated exemplary. Mind you, this is not in Texas, but I still think you can use national statistics. The way money effects education is not going to change simply because of what state you are in. District of Columbia for example has abysmal test scores, but they spend more per pupil than almost any other state. Most rich schools spend their money on vulgar displays of wealth like gigantic athletic stadiums. More than that, administrators see more of that extra money in their paycheck than teachers do. You can't exactly say that money helps keep adequate teachers with that going on.
For the aff you could argue that not all schools use their money that way, and poorer districts don't have a choice in how to use their money if they don't have any. Why be punished because of the way some rich schools use their finances?
Knowledge, the Common Good, Capitalism, Validity of the Constitution, and the American Spirit are some slightly less common values if you need help there.
I'm really glad I found this place. It helped me get a good start on my cases. I'm running American Spirit and Education for the Aff. Probably gonna use Capitalism and Validity of the Constitution for the Neg. You can go to
http://www.capitol.state.tx.us/txconst/toc.html to see a copy of the Texas Constitution. I'm fairly certain the Robinhood Plan violated Article 7, Section 6. It says something in their about how permanent school funds that districts draw from the county can only be taken away through the county commissioner (if I interpreted correctly), so unless every county commissioner agrees to it, it violates the constitution.
