While we all would hope, perhaps idealistically, that our politicians are involved in government because of a will to help others we have to accept that for some it will be just a job.
You could argue that for most there has to be more to it than that as some could make more money outside of politics; some but not all.
But of course apart from a salary there are expenses to claim, functions to attend, networks to grow and side earnings to consider. Power is an aphrodisiac to some which explains why some of our politicians get embroiled in sex scandals and maybe why some look the way they do; if there was ever a politician deserving of contempt though it is Danny Alexander.
Remember this Liberal Democrat who was an integral part of a Tory Lib Dem coalition government for five long years.
Labour's Harriet Harman called him a ginger rodent but ultimately she apologised; few outside of politics would bother apologising.
She did however apologise to all other Scottish redheads rather than Alexander.
This red-headed Scotsman sat in parliament nodding like one of those dogs that sits in the back of some cars as David Cameron and his Chancellor George Osborne savaged budgets for some of the poorest people of the UK.
Often looking like the cat that got the cream, the electorate nationwide gave a satisfied smile when Alexander, 43, lost his parliamentary seat in 2015.
But what would this man do post-politics?
If you ever wondered why he, and his Lib Dem and Tory chummies, always were soft on the banking system even after it wrecked the UK economy read on.
In August 2015, three months after losing his parliamentary seat Alexander was handed a knighthood presumably for services rendered during his time in coalition working alongside Tory Chancellor George Osborne.
In October Bloomberg reported that Mr Alexander "is in the running to join China’s Asian Infrastructure Investment Bank, according to two people familiar with the appointment process."
It looked like some in the UK would be helping Alexander secure the banking job although there were reports that he was not likely to be given the role.
He was duly nominated by friends in the UK but in January the FT reported "Beijing ‘unimpressed’ by Danny Alexander’s nomination for Asian Infrastructure Investment Bank."
The report continued by saying the company was not impressed at the UK's choice for their "high-profile new development bank and has placed him in a job heading communications. Sir Danny will have a vice-presidential role at the Asian Infrastructure Investment Bank, but China is not impressed that Mr Osborne has chosen to send a “former politician”."
Two days ago the Financial Times reported "Danny Alexander has been confirmed as a senior executive at China’s new Asian Infrastructure Investment Bank, a hotly-contested role that makes him the leading British figure at the body" and leaves the rest of us smelling a ginger rat.
Friday the Herald of Scotland reported "Treasury confirm Sir Danny Alexander appointed to high-powered banking role in China" leaving his new role in no doubt.
So where did Mr Alexander fit in the political spectrum - career politician, man with principles or total self-server?
