When it is required that all paychecks become direct deposit - it is only a hop skip and jump away from having them remanded to someplace other than your banking institution. This requirement can be imposed by SSA on the basis of 'tax collection' efficiency. There is paperwork suggesting this start by a future date - like 2015. Hold on to your hats. Cash is king.
This was recently floated as an idea in the UK, I kid you not.
“When it is required that all paychecks become direct deposit...”
that is already so for all military and federal government paychecks, as well as social security benefits and the like. Next step is the rest of you...
