I'm glad you support a system which allows Children to access only one form of Education - "Public Schools". I'm not the greatest fan of vouchers, but it allows some pupils to access higher levels of education that their economic level would not have previously allowed. (Even if that standard of Education is still industrial and sub-standard, but anyway..)
Emphasis on some students. My main problem with vouchers is mainly that unlike public schools, private schools
can legally discriminate in their admissions process. That makes any "competition" between them and public schools extremely one-sided. Vouchers don't improve education, they effectively turn public schools into under-funded dumping grounds for all the "undesirables."
