Edukashun: a quick question

To all those who favour vouchers/bringing back grammars/privatising the education system/shooting anyone so genetically-inferior they work for the public sector:

Here's some facts, provided by the Telegraph - although I'm sure they didn't intend do.

Here's two more: Finland has a comprehensive system; Sweden has a voucher system.

Why isn't Sweden doing better? Could it be that structure doesn't matter that much?

Or it does matter. This means you're still wrong.

Have to go now so please feel free to admit this in the comments below and I'll read them later.

Thanks.
