@georgeob1,
She used the once-in-a-millennium opportunity of benefits from North Sea oil revenues to fund redundancies in the workforce thrown out of work.
No infrastructure improvements, such as in France
No investment in agriculture, as in Holland
No social wealth fund, as in Norway.
Only profits for investors as public assets were sold off cheaply.
(btw "brown coal" is not mined in Britain, even before the pit closures, as far as I am aware)
