Below is a chart showing estimated spending in Pennsylvania under Senate Bill 1 (this assumes $50 million for opportunity scholarships, $75 million for EITC scholarships, and the 2008-09 actual spending by public schools).
The Pennsylvania School Boards Association and other defenders of the status quo have claimed that the voucher plan would "drain funds" from public schools. That is to say the blue slice of the pie is too large.
What's that? No, the blue slice. Well, get a magnifiying glass out if you can't see it. It's there I tell you.
