It's totally Ticketmaster scumminess if transfer fees are ridiculous (see pavel_lishin's post). Likewise if Ticketmaster has difference standards for Big Scalp versus retail scalping. But the existence of scalpers (arbitrage traders) is inevitable if a) tickets are underpriced and b) tickets are transferable. You'd have apartment scalpers for rent-stabilized apartments if leases were transferable (which they are not).
When demand (concert-goers) greatly outstrips supply (seats), you have three options: long queues (the historical socialist approach) or lotteries (the egalitarian approach), high prices (the market economy approach), or corruption (the current approach). There is no realistic solution that makes everyone happy, but you can choose the kind of unhappiness you get. There is a strong case to be made that the artists do not want to be seen as greedy merchants, so they underprice their tickets and offload the anger onto Ticketmaster (see kevinsync's post).
