Welfare states can kinda work if:
>GDP per capita is already high
>Institutions are sober and solid
>They're structured in such a way that profit can still be had
>Population is cohesive and homogeneous
And even then, they can often lead to crushing debt problems if inefficiently ran, and possibly create some negative side-effects (like devaluing the family structure and making people irresponsible).
Most important, though, is the last point. Germany and Sweden will collapse if they keep importing enrichers.
