I think, Bitcoin has the potential to reduce unemployment. Unfortunatly so far no real Bitcoin based economy has been developed that would actually give people some true and lasting business oportunities. There si someting here and something there... some business people accept BTC as payment but any real work oportunities for the general population have not been put out yet.

On a second not most Governments probably wouldn't want that to happen anyways, because with bitcoin they have no way of checking on you in regards to taxes.
