I'm not sure if this is the answer they're looking for, but a quick google search tells me that the commercial production of chloroethane is by the reaction of ethene with HCl over an aluminium catalyst. This is obviously an extra synthetic step over simply reacting ethene with benzene and hence will cost more money.

Ethene is a direct product from the petrochemicals industry cracking process. It has to be cheaper for that reason.
