Exactly what makes you think that metering is only about reduction in usage?
Water charges were not "introduced to pay back the banks". We didn't "pay back" the banks. We yanked them out of a gaping hole that they had fallen into. And water charges alone would be a very, very, very, very, very long time managing to put a filling in that particular cavity. Water charging was included in the agreement concluded with the Troika because it was one of the REALLY obvious gaps they identified. Something that should have been in place a long time ago but was never politically expedient for FF to implement. We had a tax system that was insufficiently broad and was too dependent on property transactions.
I can't agree you have presented any tenable case. if you are the prosecution you are hardly fit to present in any court. Your entire case is based on the fact that you are in no doubt it is true - hardly a convincing argument. "It's true cos I say so"
FF agreed the bailout, FG/Lab largely implemented it. Protection for the vulnerable and the lowest waged was one of the things Labour in particular endeavoured to ensure. The burden of paying the cost of austerity (despite what the loony left would assert) fell largely on your so-called "middle class". That does not mean they were "mugged" - a particularly emotive word frankly. We all form the state, those of us in a position to pay were largely "middle-class". In large part, by September 2010 the banks were close to (or already) insolvent. What that means is that they did not have money. There was ZERO point in attempting to extract money from them. By nationalising them and keeping them running we managed to have a country that didn't descend into widespread anarchy (much to the chagrin of the Anti-Reality Alliance - they'd have loved a nice revolution handed to them on a platter). When they are sold off the state will be in a position to recoup at least some of that. In the meantime, the banks have actually been paying back monies the government provided to back them.
it is silly and ill-informed to assert they never touched the banks. After all, some have been destroyed (Anglo), most others were nationalised (AIB) and even the one that wasn't nationalised had a large lump taken on by the state (BOI). All of the banks were touched. (Some might say many of the bankers had probably been touched in the head for years but that is a different tale). But there was no pot of gold there for any government to draw on. And even if there was - that pot of gold would have still been the middle class who actually use the banking system.
You have not proven anything. Get yourself some facts first.
