You are literally choosing to dismiss data that destroys your argument while providing none which supports it. Your opposition to teachers unions is clearly based on your emotions and ideology rather than any facts. Please do better when posting on HN.
correlation does not equal causation homie. a US news listicle with a method of ranking doesn't mean anything. i can find a list that has mass towards the middle or bottom depending on the bias of the ranking i share.
I’d love to see such a list! In the meantime your argument is convincing in direct proportion to the quantity of data you have provided :)
