Navagon: As far as I'm concerned if other countries want us to pay benefits to their people living in their country then they should pay those benefits themselves. Anything else is unjustifiable.
I am maybe not fully sure what the issue is there, but isn't that the same for all EU countries? Does UK feel they alone are hit by this? I recall similar concerns here, for Estonian workers coming here (especially in the building industry).
I find that a bit problematic thing. If foreign workers are not eligible for (your or our) social security, doesn't it also mean they shouldn't pay taxes to the target country, but to their own country? So when Polish construction workers come to work in UK, they would pay all their taxes etc. to Poland, not UK, right? I don't find it quite right either that one would have to pay taxes to the target country, but not receive any benefits from there.
Or if the issue is specifically for someone receiving benefits (for unemployment, pension, whatever) while living abroad, doesn't that apply also to UK citizens who have chosen to go live elsewhere, e.g. Spain or Thailand? Should their benefits be cut off because they are not on the UK soil anymore?
As said, I feel this issue is rather complicated, each "solution" can be considered unjustifiable in some way. I can't say what is the correct answer to it.
Navagon: Pretty much every party, once in power, winds up doing more or less the same centralist things irrespective of their claimed political leanings. UKIP would be little different.
True, that happened also to Perussuomalaiset here. Once people get into power, their main concern seems to become to stay in power, even if it means selling their principles. Very rarely I see the opposite. Well, the leftist party here did leave the earlier government (because they felt it is doing too right-wing politics), but I felt it was more like a political stunt as the next elections was already getting close.
