The top price for U2 is too high, can't argue that. The rest are pretty fairly priced. GA being in the region of $50 means people can get close to the stage without paying an arm & a leg which is infinitely preferable to paying $2,000 for the "privelege". There are something like 10,000 tickets for every venue at $30 and 85%+ are priced at under $100. In addition their tour is costing $750,000 a day to run so somewhere that is going to be paid for by someone.
