Greece is facing severe economic troubles. Its national debt as a percentage of GDP is a cause for grave concern. As this article makes clear, all this has also impacted Greece's ability to care for its cultural heritage. See http://www.theage.com.au/world/economic-woes-cloud-ancient-greek-glories-20100227-pa2x.html The crisis is so bad major cultural sites have been closed. Even worse, corruption and waste has eaten into what funds are available.
Greece needs to rethink its priorities. State control over everything "old" only exacerbates the problems of severe underfunding. Greece should allow a licit market in redundant artifacts and tax it so monies can be used to fund Greece's underfunded cultural treasures.
