We - or at least I - have lived through a time of huge economic and social change.
When I started work, a computer was an industrial curiosity with punched card input , numerically controlled machine tools were rare, and manual payroll records were common. "Made in Japan" was a term of derision and "Made in China" was unheard of. British Leyland were the largest UK car manufacturer and a car was worn out by 40,000 miles. "North Sea Oil" was a phrase, production had barely started.
Since then, almost all repetitive jobs have been automated, a car contains computers 100 times more powerful than the first Moon Lander, much production has been outsourced to China or the Far East, BL no longer exists, "Made in Japan" is a badge of quality, cars last 150k miles + and the UK coal industry no longer exists - decimated by production costs, geology and the Clean Air Act.
To blame these changes on one politician seems to imply she was all powerful : the reality of course is the world has changed and the UK had to as well..
But UK politics has not: one man one vote every five years and then politicians do what they like...
I have written to my local MP twice in my life: once before the Iraq war. The Labour incumbent dismissed my concerns out of hand.
And once before the proposed Syrian intervention. The (successor) Tory incumbent dismissed my concerns out of hand.
As you may imagine, I was underwhelmed# at being proven correct before the event - with the Party Whip taking precedence over argument. I can see how WW1 began with such stupidity.
# a polite phrase.
