"If". How about people cross that bridge when we come to it, which unfortunately for the wannabe revolutionaries in our society, most certainly won't come...
I just know the way governments get out of doing things they don't politically want to have to. Claim that it isn't affordable, implement some deckchair rearrangement on deck and brush it under the carpet. All I'm saying is that it's part of thre social contract that the people hold their government to account. Party allegiances are (or should be) a secondary consideration. If one thinks that something out to be done when the 'other party' is in power, logical consistency demands that one feels the same when one's preferred party is in government.
