@TheGoldenMole Well now, GM. This is something I've often thought about. Obviously, me being me, I would incite a social and economic revolution. But it's interesting to note that I wouldn't need to spend penny one to infiltrate and finesse the current political classes, or to appease capitalist-minded members of the general public (which is where Corbyn's Labour is going wrong).
You'd just need a relatively small amount of capital to build new housing, start non-metropolitan, non-stock-markety businesses --which you'd run along socialist lines-- and then the whole thing would slowly pay for itself. And then, once you started turning a profit, you could then use that cash to buy-out all private health companies ...and then you gone and dun it, boy, jobs a good un, civilization saved.
