Untrue: for example, if you are a lawyer employed to help a company acquire real-estate or another company (i.e., a merger) then your salary is treated the same way by the US tax code (i.e., your employer must amortize your salary).

If you want to argue against the current tax code, point out that currently companies do not have to amortize the pay of executives even though arguably their work fortifies the company's ability to make a profit in future years like the work of software developers does.
