” Unless all the states were to elect socialist governments at the same time..”
I hate to be gloomy but I think this door has been shut as we saw in UK and US and movements that show some semblance of paying lip service to socialism or even wish to maintain welfare elements in their governance are under constant attack on all sides. Even in the interwar years capitalism has survived because it adapted by tinkering and went along with the powerful swell of demand for a welfare state, partly because at the time this also helped capitalism recover because it needed consumers. The open hostilities became obvious when workers and trade unions got too powerful for the interests of capital.
The situation will only get worse because of not only globalisation making corporations above national laws, but because computerization and advances in robotics will make many jobs redundant and those few who can afford it will have vast powers. The only use for the 99% will be as consumers of the products that will keep the 1% getting richer. Maybe the focus of the new industry will be to manufacture robotic consumers to replace the consumption by the then unemployed and useless to capital majority.
Unless there is a new revision and someone can reverse these trends I can see no easy way out of this gloomy future of market capitalism.
