brit, what I meant to say is that if people come from regimes that execute stringent control it is, IMHO, almost impossible for them to function in an environment that lets them decide for themselves to a large extent.
Those whose ancestors were raised under those controlling regimes, may or may not teach their children values that were predominant under those regimes, and are not applicable in their new country.
And, last but not least, taught cultural values often, as we see, conflict with those values in the "new" countries.
