I agree that the Conservatives have put in place some decent measures to help the working class - the income tax threshold rise for instance. But don't forget that correlation does not imply causation. Unemployment during Labour's firts few years was significantly lower than that of the Thatcher years, and the global financial crisis put paid to this impressive record continuing.
We also have to contend with the fact that although employment offers a form of security, it alone is not sufficient to help the working class - this needs to be supplemented with good quality conditions, high morale, etc. On these aspects, I cannot find many positives with recent Conservative Party policy.
