Conservatives have always been pro privatisation.
Nationalisation saves money, but causes taxpayers to pay. Wealthier people pay more tax. Therefore, under nationalisation, the rich overpay and the poor underpay. This is also called "society".
Mostly, the areas where the Conservatives get most votes (and seats in Parliament) are more affluent areas and therefore the majority of Conservative voters want privatisation so they pay the same amount as the least wealthy.
I would also point out, that while the Conservatives kicked off privatisation in the early and mid 1990s, Labour continued, if not, picked up pace in the late 1990s and 2000s. For example, Conservatives started privatisation of railways giving contracts of up to four years to private companies, but Labour continued with their plans and have issued contracts up to thirty years.
The largest political party against privatisation is the Liberal Democrats.
The problem is that too few people are interested in politics. Too many people don't seem to understand that politics effect them. They are happy to moan about rail fares, about selling utilities to multinationals in other countries, about laws they don't agree with, but when it comes to election day, they don't vote or they vote for parties without knowing what they stand for. People need to take an interest.
Too many people cannot name their MP. Too many people don't know what party they stand for. Too many people don't know how their party votes.
www.theyworkforyou.com is about trying to make people realise that their MP work for them. You can get a list of every vote by every MP in Parliament. You can get e-mail alerts every time your MP votes in Parliament.
Until people realise that politics affects them, things cannot change.
Wake up people!
