I believe both his parents were Jewish. So he is a Jew in name only (JINO). His attitude toward Israel is negatively influenced by his company's financial interests in the Arab world.
Speaking of the NYC public school system, I'm no Bloombutt fan, but there are other factors involved in the schools aside from him and his lackeys. The pupils are in large percentage uneducable, because of the destruction of the American family unit that has been getting ever worse since the onset of LBJ's Great Society in the 1960s. It's going on just about everywhere in public schools, especially in big cities where so-called "minorities" and immigrants tend to form the bulk of the kids in attendance. New York public schools are probably no worse than, maybe even better than those in cities like Washington, Detroit, Newark, and Chicago, to name a few. Kids raised in dysfunctional families will not have any desire to get anything out of their schools until and unless some mentoring figure gets tough with them and lays down the proper approach to learning. Public school teachers can only do so much in that regard without help from others who can be positive influences on the kids.
Of course, liberals like Bloomberg can be legitimately blamed for the public school mess in the sense that they brought about massive social programs which helped to debase the culture in which the kids are living.
What you say certainly is true. However, Bloombutt and his minions most assuredly hold TEACHERS responsible for every failure.
