They do, but only for specific definitions of "work". Like, benevolent dictators in Cuba 100% raised the literacy rate by an insane amount in just a few years (something like 20% => 80%").
If you define work as "literacy", they no doubt succeeded. But if you consider the people (and children) they tortured, raped, and murdered, suddenly literacy doesn't seem so important.
