Here are just a couple since I am in a hurry:
-While people may have wanted "investment in education" this should not mean massive wage increases. Investing in education logically should be more teachers and better schools not necessarily more money for the existing teachers. When one looks at the number of un and under employed teachers supply and demand is broken so wage increases on the scale they did were unjustified, while little was actually accomplished on class size etc.. But I do not want to single out the teachers, this has been seen across the board in the public sector in Ontario (teachers are just one example), he bought union votes and union peace via big union wage increases and the expense of the tax payers. Ontario public sector
-You were pretty dismissive of the hydro plants/ORNGE/EHealth but on his watch all of these things happen, and this is waste and with maybe corruption as the median. Just on the Hydro plants, proroguing the legislature had a lot to do with covering this up and protecting the his energy guy from possible jail time as it did anything else. If he did not prorogue when he did the Energy Minister would have faced contempt of the legislature charges OR he would have had to come clean. Lose - Lose for the Liberals so prorogue it was to save their own.
-Brings us to proroguing the legislature, quickly covered the hydro plant deal above. How can anyone call his actions anything other than what it was, a coverup, and with his government about to fall, prorogue to save the party. Not like they are the only ones to do it (fed cons), but we are talking about the Ontario Liberals...
-Full Day Kindergarten, now this one was a great example of unintended consequences (and more money waste). His idea was instead of investing in childcare lets just take part of it over. Now the teachers said this was a bad idea and the curriculum was more than lacking, but in his mind what do they know HE is the education premier... What has happened, they mostly targeted low income areas first. This took the 4 and 5 year old out of daycare and into full day "care" at the school. These kids were the bread and butter of the daycares, based on age the number of daycare workers decreases (by law) as the kids get older. So this took the money makers out of the hands of the daycares leaving them with only the operationally more expensive younger kids. This has actually closed daycares and in general made daycare harder to get for low income families! Yet he just kept plowing forward...
the list goes on but this post is long enough
Sure, there's always something to criticise. I still don't see how any of this makes him to blame for the debt load. Nor does it support accusations of "fiberals"(TM Toronto Sun) or of corruption, just slimy politics like I said. In any case parliament has been back in session for three months, we'll see if anything comes of these accusations or not.
