The increase in arrears is, obviously, of concern but my point was that this has occurred in a relatively few pilot areas.
A knee-jerk reaction would have been to introduce it nationwide without any study.
I wish governments (all of them) would carry out more assessments both of possible new policies and how current policies are working.
But, they won't do that if we leap down their throats when a study finds there are flaws. We should say 'Well done - you've found problems. What are you going to do to deal with them?'
If we don't do that, they'll carry on blustering that a policy works (creating numbers that seem to show that) and ignoring all criticism.
