The bank issue is a Maggie creation through her deregulation in the 80's. not only did it affect the industry itself, it re shaped the national attitude. No more do we save and spend if we have it to spend, we spend what we don't have and are paying the price.
She had some good ideas but without the follow up and balance. Allowing council tenants 'right to buy' was inspired, it inspired the working class to strive to work and buy their own homes, but then not to reinvest that money into more social housing was ridiculous, a disaster.
I can appreciate that whole communities have been wiped out when coal and ship building went, but that was inevitable too. Coal was getting too dear to mine (plus Germany paid its reparations in coal which undermined our coal industry) and cheaper world alternatives were available. Add into that that British coal isn't very clean burning so won't meet the green credentials of a modern era.
Shipbuilding had been in decline long before Maggie got in too. Cheaper and more innovative producers took their toll.
When whole communities depended on a dying industry then this was going to be devastating. The shipbuilding industry should have been better supported to innovate by government contracts.
Where this country is lacking is in investment in innovation and invention. Unfortunately we rest on our laurels, trying to eek out every last penny from an idea and then wonder why the rest of the world takes over! I agree with not protecting outdated, uncompetitive industry as that's pouring money down the drain, however that needs to be balanced by investing in research, innovation and investment. Its that that the Thatcher government failed to do. It cut investment in the dead ducks but didn't strive forward to replace it with anything and that was unforgivable.
I do believe in the free market economy by with responsibilities and safeguards. The Thatcher era promoted the free market economy but without the responsibilities, safeguards and humanity.
