Greece is facing these strikes becasue of a cut back in government spending
What do you think is going to happen in the US when the various government cut back on medicare/medicaid, unemployement benifits ect.
Overall the US is going to face spending cuts of a very large degree, meaning lots of people with alot less money.
Now unless Americans are a more passive lot then the Greeks or some other European countries, I will expect some mass civil protests. Not so much a nationwide strike, but very large demonstrations
Imagine what those that were upset at the possibility of having "their medicare" being cut to fund socialized medicine (Irony) actually having benifits cut 30% or more.
