The political split has become much easier to see now and in a strange twist has partially reversed.
20/30 years ago, folks in the private sector / employed eg. manual workers, white van man, railway workers etc “working class” = Labour and they made up a large section of society, often in unions. There’s no “Trades Union” members anymore, just teachers, nurses and civil servants - not Unions who stand up to unscrupulous big business owners, people who instead try to get more out of the tax fund provided by working taxpayers. The gulf in standards between private sector pay and conditions and public sector is huge. (Waits for some chump to say “we need to make all jobs have huge rights and benefits”. - clue - employers are stretched beyond as is and we will just see more firms fail).
Contributors v. Non-contributors has tipped. Non-contributors (government staff, schoolchildren, pensioners etc.) is a growing element along with the “I’ve got mentel ‘elf innit” youth. (Look not all, but too many taking the p-**+)
So now we have a huge part of society with a false view of the economic realities.
The civil service is bloated beyond belief. The NHS is hugely inefficient and we plunge ourselves into deeper debt whilst people jump round with “refugees welcome signs” (do we think those are contributor types?)
The split:
Those who get money from the government (civil servants, NHS, unemployed)
Those who get money from private enterprise.
Latter is shrinking and fed up with non-contributors who often spout nonsense and vote left.
