Sweden is able to be a successful Democratic Socialist nation because of the unique culture of the Swedish people. Deep down it depends on the good will of all the people. The same experiment would not work in all cultures. It is like a delicate orchid, which needs very special care. This is why, this ideal does not organically form all over the earth. One of the main problems with too much immigration is, if there is not enough assimilation to the orchid's growing medium, the new composite soil, may not be as optimized to this very delicate flower. The Swedish example, cannot be found anywhere in the middle east, since those cultures are not conducive to this experiment. Does anyone think you could transplant Democratic Socialism to Syria or Iran, without bloody wars and lingering grudges? This cultures are old and set in their ways. The problem this orchard faces is if the soil is changed too much by immigration, not conducive to orchids, this unique orchid may stop growing and flowering. It may go extinct, never to be seen again. The world needs to preserve this unique experiment, so we can study how and why it grows, there.
