Ticket prices here in Brazil (where I am currently living) are even worse than in the US.
The high prices are somewhat justified, as production costs are higher than in the US... South American tours usually have less than 10 dates, what makes the cost of flights and visas more expensive per show, as you can't dilute it between a 25 dates tour. And the entire tour is done by plane, never a tour bus.
And there is absolutely no such thing as tour support for any band...
