cogadh: To be fair, there is a huge difference between crossing a border to save a few bucks and moving millions upon millions into offshore accounts to avoid paying taxes on them.
The only difference I can see is scope. The idea is the same, to avoid paying taxes as much as one safely can. I am not convinced at all that that someone who saves "only a few bucks" would be any more likely to act more morally(?) as a millionaire.
From the rich guy's point of view, they feel it is unfair the whole welfare system is financed from their(?) money almost exclusively. Not saying that is the right or moral way to think, but that's how most people in the same position would most likely feel.
Show me a person who has e.g. earned a fortune during his lifetime, or even just won it in a lottery, and is willing to give most of it to finance the welfare system, rather than e.g. securing the lives of their own family and offspring, and I'll show you... my dick (sorry I couldn't think of anything else to show right now, I hope that'll do). I guess there is always Bill Gates and such, but I always feel they have some other agenda there like teaching their kids to earn their own fortune, or go to history books as a big benefactor...
EDIT: Oh yeah, that is also another thing I find funny. When I ask these concerned citizens isn't it wrong that Finns don't have to pay taxes if they win in the national lottery (ie. they get the whole sum to themselves), they don't see any problem with that. They don't also seem too concerned that e.g. a local Formula One hero like Kimi Räikkönen is not registered to Finland, but is registered to some other country where he doesn't have to pay as much taxes.
Double standards, the angry mob is more likely to give a free pass to lottery winners (especially knowing that they might become one as well at some point), local sports heroes, singers, actors etc.
