My worry is with all of the JC promises where is that money REALLY going to come from?
I thik it's going to come from the same place that all those billions for quantitative easing came from (far more billions than the LP plans might involve). I don't see anyone complaining about that.
The difference being that QE kept the banks afloat and protected everyone with bank accounts but we've seen nothing of it beyond that. It didn't stimulate investment or create new jobs or 'trickle down' to the general economy. (OTH, it didn't create huge debt, either. The tories did that post 2010*) The LP plans are intended to create jobs, create work for businesses of all sizes and give a return to the Treasury by way of taxes on this economic activity.
I recall studying the 1930s Depression at uni and one of the secondary effects of the house building programme was to create a demand for consumer goods which helped to stimulate the economy.
Of course, it's difficult to pick economic holes in the Tory manifesto because so little of it is costed.
*Anecdotal so disregard if you wish. The medium sized transport company my DP was working for in 2010 had as its main business the transport of sand, gravel and related building materials. The work just dried up once the tory austerity programme got under way. Which, of course, led to 'rationalisation' of the workforce...out of decently paid jobs and on to benefits with reduced spending power (or massively increased debt)
We have to make the connection between our consumer driven economy,employment, decent wages, and growth, as well as focussing on exports. They are both important.
