I think what it will mean will be loudly trumpeted investment in job creation in 'red wall' areas, which will bring low-paid insecure work that makes profits for rich people who live elsewhere.
Local employment figures may fall as a result, and this will be presented as having happened because of government policy and Brexit. People who are on benefits will be coerced into taking jobs and contributing their labour to the profits of the company owners, on pain of starvation and the approbation of workers who will be told that 'scroungers' are being paid directly from their taxes.
Insecurity of pay, uncertain employment and unsociable hours will mean that children grow up without parents or carers around when they need them, and their educational attainment will suffer, but they will form the next generation of the 'precariat', and profits won't be affected, so that's ok - there will be numerous pundits telling us that not everyone should be encouraged to stay in education anyway.
The economy of the areas concerned will appear to be booming, as it will be the companies' contribution to the GDP that is reported, and not the disparity between the wages of the workers and the dividends of the shareholders.
