> Public education is undermined by the very people who want homeschooling and public vouchers
The whole article is about how those are two distinct groups who are at odds with each other- home schooling parents don't want to receive vouchers on the whole.
In any case, public education has plenty of challenges; homeschoolers are the least of them.
From the utter lack of involvement of parents (child tardiness, behavior issues) to lack of teacher authority (unable to prevent disruptive behavior from derailing classes) to some districts having too many students who don't know English and not enough funding for sufficient ESL teaching resources, all the way down to funds being drained by oversized administrations and unions (remember the NYC rubber rooms?).
Some of the worst performing schools get the most per-child funding. All of that money is going somewhere, and it's not going to teaching kids.
I was fortunate enough to go to a good public school system and had friends who cared about getting good grades, but would have floundered in an environment like what you see in some rural schools, or Chicago or Boston.
