Why is it iron 2 and not iron 3?

Hi all

Upon the reaction of Hydrochloric acid with Iron.. the following equation represents the reaction:

Fe + 2HCl -------> FeCl₂ + H₂


Why isn't the product FeCl₃? I don't understand what makes it not possible for iron to form this chloride salt.. why isn't the equation:

2Fe + 6HCl --------> 2FeCl₃ + 3H₂

You will have to compare redox potentials to see the reason. H⁺ is not an oxidizer strong enough to oxidize iron beyond 2+.
