Regarding information gathering: personally, I'm a facts kind of girl. In particular, I'm interested in comparing the politics and social issues of healthcare in the US vis a vis the UK. I'm curious about stuff, like say, since there is public transport here to a greater degree, is that worked into NHS benefits where it is deemed reasonable? I'm not interested in pocketing the information away for future use necessarily. But that's not really the point. What if I *were* to be poor and considering a pregnancy that would be expensive? That brings me, er, to the point I posted in the wrong place *cough*.
To quote myself, whether people agree with it or not, the existence of socialized healthcare removes a lot of the justification for argument. A person might resent me for getting pregnant again. Another might resent a person for smoking. Another might resent a person for not aborting a seriously disabled child. But what really is the point, aside from exercising your right to make others feel guilt? There is no reason for a values discussion ever, really. It's not like the government is going to start picking and choosing who gets their healthcare paid for anytime soon. Because of unfortunate events in my first pregnancy, to balance the playing field of reproductive rights, I need costly procedures. I fail to see how this is fundamentally different from the person who wants a heart transplant in order to exercise his right to live as long as possible. This is one reason why I think progressive ideas like socialized healthcare are a good thing; people become defined less by their cost and more by their needs. At least that's the idea. Apparently there still exists a lot of 'american-style' sentiment that a society has more to do with who benefits society and who burdens it and less to do with a society with aggregate needs that need to be taken care of.
So, should foreigners ask about benefits? It depends on who you ask, and what they're going to assume it implies about you and your choices.
