Reply to Tom on vouchers, etc.

Tom asks if I agree "that even the interests in 'religious freedom and value-pluralism' can support graduating the voucher amount by income (perhaps cutting it off above a certain level)?"  Oh, sure -- given the political realities (i.e., a public-school baseline is here to stay) and the realities of financial scarcity, I definitely agree.  But, I also believe that the approach that would best serve the common good, properly understood, would be universal (and equal) voucher-ization of education funding, with government schools being one co-equal option among many other (reasonably regulated) options.
