Certainly not across the board, and especially not in poorer areas that cannot/will not fund their schools. That is an incredibly general statement that simply is factually incorrect.
Thank you for the source, this is rather interesting. However I believe there’s some level of miscommunication. My original comment was in reference to the inequality within the distribution of funds due to inequality of tax revenue across the country, and how that affects the learning opportunities of less-privileged kids who, I would argue, are in more of a need for better education to escape their lower income bracket.
