I lean towards agreeing with you more than agreeing with the article. However, I don't fully agree with either. The problem is with both. There are plenty of parents who do try to put in effort to help, but meet with teachers who don't care enough to put in their side. Yes, the parents could remove their child from that classroom or school, but not every parent has the money to have their child transferred. Things aren't always so black and white (pun intended). There's definitely an overlapping area where both the educators, the government, and the parents can all work harder or be to blame for different issues.
My best friend is a school teacher, and I here stories from here on both ends of the spectrum. About teachers who don't teach, and parents who don't parent.
Also, the government should not be removing teachers who are already in place and culturally adept and replacing them with fresh faces. They should be re-training the people who are currently in place.
