I can see why she would go down that route tbh.
A huge amount regarding working class dissatisfaction has been publicly & widely reported over the last few weeks; only a fool or the wilfully ignorant could have missed it.
Tories used to appeal to blue collar working classes as well as the rich - they have been losing that link for a while now (probs to UKIP, just like the traditional working class Labour vote).
It is blatantly obvious to anyone with half a brain that if you appeal to the massive disaffected working class vote, then you're practically a shoe-in for the next government.
Labour are still too concerned with their own infighting and power games to seize on this, the Lib Dems are ineffectually flapping around, still trying to court the Left-leaning-middle-class-BrexitDrama! vote and the stage is wide open for someone to fill the gap.
Step forward Theresa May with this sort of promise and the heads of millions are turned.
At some point soon, I live in eternal optimistic hope, the political elite at the top will realise that government & politicians are there to serve the people & not their own egos.
