All I can suggest you do is some research for yourself Usram
Differant Britons had very differant experiences of Thatcher, so personal experience is not necassarily a great guide to the actual effect of her misrule.
It is very easy to dredge up the numbers though, take a look at the economic indicators and tie them up with the policy decisions Thatcher made, but make sure that you also tie in a certain amount of lag, interest rate rchanges usually take about 12-18 months to work through, however tax cuts take much less.
You’ll see that that 20% tax cut in the higher band coincides very well with an increase in inflation and the consequent increase in interest rates, which then ties in well to the boom and bust cycle.
Thatcher was hopelessly irresponsible with finance, she used a huge opportunity that no other British leader ever had, and she squandered it all, because the oil revenue supported sterling when it would have declined severely, and this would have meant a completely unaceptable rise in interest rate and a depression, not a recession.
Those oil revenues replaced the lost taxation of millions of recently unemployed, it paid for borrowing on the international markets, our need for manufacturing was reduced in national terms.
As for manufacturing being less relevant as low cost economies begin to use cheap labout, why do Japan, and Germany see manufacturing as being crucial to their prospects then ?
British investment performance is very short term, it is very dynamic very profitable, but commodity trading will never employ the masses.
British industry has been seriously let down across generations by its ‘Captains of Industry’, you can look at just about every major industry the UK had, and trace its decline to poor short term investment decisions, from ships, motorbikes, cars, to almost anything you can think of.
The problem in the UK is that as far as developed nations were concerned, we were a low wage economy, its cheaper to get a quick return using more workers and outmoded equipment. I personally worked in the 1990’s in a company that had machines dating back well over 100 years, some of those very same machines actually made the suspension springs for the Rolls Royce Silver Ghost, they still had all the dies to manufacture suspension springs for horse drawn mail coaches!
Germany and Japan went the other way, they used fewer workers, preferring to develop industrial technologies that enable them to employ fewer workers, but much better paid.
One of the reasons for the rise of the unions is simply the appalling way British workers were treated, look at the casualisation of the dockworkers for example.
Had British capitalists looked after thier workforce the unions would not have developed the power they did.
There is a good old capitalist saying,
“There are no bad workers, only bad managers”
Its as true today as it ever was.
If you look at the Nissan plant up at Washington, you find British workers with modern plant can produce and compete with any other similar workforce producing cars, the reason that other British car manufacturers had such low production rates was largely down to investment.
