Like Cohiba cigars and Bushmills whiskey major league baseball tickets are not one of life's little necessities. I'm a firm believer in the free market and if the owners feel they can get more for their product more power to them.
However, I don't want one red cent of taxpayer money used to finance "more modern facilities". A number of major American cities are still paying on multimillion dollar bond issues for stadiums that were long ago hauled to the rubble heap. The Kingdome in Seattle, and Three Rivers come to mind most quickly. If a major league team threatens to leave town because the citizens won't pay for their new facility I'll be more than happy to show them the door.
Think of those increased ticket prices as a "user fee" to finance those new stadiums the billionaire owners, and millionaire players just can't get built any other way !!!
A new stadium for the Cubs? They'll win a World Series first.
