did you know the nordic countries are among the happiest and have some of the strongest social benefits in the world while still being wealthy?
I do wonder how much of this is due to cultural homogeneity and the benefits that follow. Will this remain the case in the presence of a larger proportion of immigrants? I don't think its a fair comparison, when people contrast Nordic countries with the US.
Many studies have found that social trust is higher and easier to maintain in homogeneous societies.
Unions have whatever powers they've been allowed to have by the country they operate in, just as do corporations and police forces.
[0] Where you put the line between balancing the powers of unions vs. corporations is one of the major political dividing lines for the last 175 years, I'm not going to do it justice.
