However....
It's one thing to be a newly minted college grad, and another to be out in the field for a while, and then be laid-off, like so many have been in the past several yaers.
Once you get experience + higher wages, it's very, very difficult to find a position that pays the same as the old one, if you can find one at all....
On thing for sure, there will ALWAYS be a need for salesmen...
