The DUP have to look after their own people first. I can't blame them for that.
The DUP, SNP, Tories, Labour, Lib Dems and all the rest have no thoughts about "caring for their own people first." Unless you mean caring about themselves and their cronies.
If it were all about caring about the people then we wouldn;t have had the last 2 years of politicians trying to work out how not to fulfill the result of the referendum yet sell it to the public as fulfilling the result. "looking after people first" is the last thing on the majority of politician's priority lists.
It is all about trying to do as little as possible while making it look like you have done loads.... and anybody who has worked in large companies knows that people like that nearly always manage somehow to fast-track up the ladder while their colleagues that actually do most of the work mutter under their breath.
The BS of "office politics" was one of the reason I ended up leaving "ambitious" office based jobs to work on the shop floor in an egg packing factory. It is one of the reasons I enjoyed that job more than the office jobs too. Just normal folks, no-one thinking they were above each other, getting on with the job and each other.
Offices can be awful places to work with all the egos fighting against each other in the name of "ambition." And politics is just the pinnacle of that kind of attitude and quite likely why they do not understand what normal folks actually think. Those big ego blaggers in the office are oblivious to how their colleagues see them either.
