Sharing each others work without any increase in pay simply forces the already underpaid man with a job to kick in with half his earnings to support the other fellow. It displaces one starving man with two who are half starved. It spreads, rather than cures, the contagion of poverty. It is like trying to turn back the pages of history from the twentieth century to the eighteenth. Such things just cannot be done and there is no good reason why they should be done.
Unemployment insurance is an empty slogan.
