My take on the 2019 UK Election:

Socialism, particularly at the left end, always arises as a response to perceived or real neglect, mismanagement and greed on the part of the particular right wing which is in power. Right wing Governments usually have choices based upon their collective wealth. Often they take the more greedy route, ignoring the poorer parts of their society...and so the pendulum swings.

Let not the old adage, "Power corrupts and absolute power etc." apply here. Boris Johnson et al have a golden opportunity to forge new trade ties, attract investment and build the UK into a stable thriving, HEALTHY economy.
But don't hold your breath! An element of pessimism? Well many have been bitten before!
Regarding the Labour Party, read this, written by a Socialist friend of mine:

Unlike Thatcher, Johnson was supported by hitherto socialist towns in the North. He owes them and, of course, others in need.. Careful Boris! No drawing a line across the Country like she did! And forget a Falkland-type scape goat this time!

The UK may now see itself dissolving into a country consisting only of England and Wales. This election has closed and opened so many doors. Time will tell.
