people working to help protesters...
"The Athens metro will remain open 'so as to allow Athenians to join the planned protests in the capital.'"
Wonderful. So they should send all of the bus and ferry drivers to work as well. How else are those protesters going to travel to the capital? And they might as well open up the hospitals and ambulance services as well, to make sure the protesters are getting the best treatment possible.
Oh wait. That's pretty much a huge chunk of the protesting population! oops
There's a reason why economic protests don't work. Go to the voting booths instead -- the ballot is your greatest weapon.
