If you pay a consultant they are responsible for the whole Social Security / Medicare cost. If you are drawing a salary the company has to pay half of that. Considering I run a software company, I would much rather pay for a consultant because it saves the company a bunch of money. Hey, maybe that's why I've never "hired" anyone as an employee, imagine that.
Now I don't propose to fully understand the rational for BiCorRx's current pay structure. And while it should indeed be questioned for clarification, I also understand that corporations (oh yeah, mine is a C corp) do things that may seem a bit odd in order to move forward.
