Well, it depends on what your salary is like, I guess. But
generally, costs for most services and goods are definitely lower
for us.
To be honest, looking at the situation these days, the US doesn't
seem to be as attractive a place to move to as it used to be a few
years back. 
Oh well, soon, I'll be moving over to a place with much higher
taxes, less up-to-date movie and US TV Series offerings, and less
enjoyable shopping.
