Your view on public schools seems to be that they are all terrible. Clearly, that is not the case. If it were, why would rich people in places like Montgomery County, MD or Arlington County, VA (who can afford to send their kids to private schools) be sending their kids into such disastrous environments? Highly educated lawyers, doctors, lobbyists etc. do not take chances with their kids' futures.
I disagree with you on this.
Your own school system (Montgomery County MD) has one of the more liberal curriculum available in this country. If you want your child steeped in liberal mumbo jumbo (as opposed to fact-based education) and homosexuality is normal education, by all means send them to public school there.
In my experience, many of the successful doctor/lawyer/CEO parents are too busy with their own work and social life to pay attention to such things as the specific curriculum used in the classroom. They're more concerned about the social opportunities available to the kids. Additionally, the IB curriculum pushed as the highest standard in this country is filled with pseudo-science and socialist agendas, courtesy of its sponsor, the U.N.
Good luck with all that. Just ask yourself one question - why do so many wealthy families vote democrat/socialist ? It all goes back to the curriculum.
