Whatever your views on the policies she attempted to introduce, there is no doubt that they were rejected by the people who stood to lose most should they fail. This is OK up to a point, but most of us don't get to pick and choose (and ultimately bring down a Prime Minister) if the government introduces policies we're not too fond of. So before people ask whether the Unions are running the country, they should ask whether the money market manipulators are.
That said, unless some properly costed policies are introduced which will encourage growth in the UK economy, it is doomed to suffer "stagnation." An ever-growing population requires an ever-growing economy or the end result is per capita impoverishment. With 5m working age people deciding they no longer wish to work, a similar number who never have and never will, many who do work not exactly cracking on with it, and those that are doing their bit being taxed to the hilt to support those who are not, I'm not holding my breath.
