I don't see how this would help the economy, mind you that they are going to be paying the equivalent of their fiat currency in Bitcoin, that is you will be given the worth of whatever you are earning in Bitcoin, now you have to withdraw it and in doing so you have to pay transaction fees, Bitcoin is also volatile and a dump can take a good chunk out of people's salaries.
