Many people who have a political axe to grind will obviously try to interpret anyone who disagrees with them as being automatically "supporters of the other crowd."
I think politicians who take advantage of state funded sweetheart deals at the taxpayers expense are corrupt: whether that is buying a state asset at a price far below it's market value like a local authority house, or a stake in a stockbrokers company bought by a state owned bank during the financial crisis and then sold back to the management when the taxpayer has bailed it out.
Political activists benefiting from buying public assets at a lower than market value price just because they happen to be in possession of the asset is wrong. Public representatives complaining about a "sweetheart deal" when they themselves are beneficiaries of similar "sweetheart deals" are typical hypocritical grifter politicians, no matter what social class or political grouping they belong to or claim allegiance to. It's just barefaced lying. But as a former minister was caught out saying, "isn't that what one tends to do in an election campaign?" It's almost as bad as claiming that you don't have a bank account, or that the granting of a lucrative mobile phone licence was done in line with fair and open procedures.
They're all the same.
