Maybe not--but maybe they just aren't all selfish bastards, but know that vouchers create competition which would put pressure on the schools to perform.
I hope you are right, about the schools, and since I do believe that a majority of the working families children will be left in these failing schools, I hope it doesn't take too long for that competitive idea to kick in.
But as not all being selfish ________, just too cynical to buy that. If their agenda meshes with ours, but unless it does - I don't think so. This is based on purely on recent history - as in the last 50 years.
