Margaret fails to mention that businessmen and women have many tax writeoffs that working people including public sector workers don't have. These include, but are not limited to, restaurant meals, which they call business expenses, transportation, including purchasing automobiles, annual depreciation on them, gas, maintenance,  etc.; holidays they call conferences, hotel stays, office supplies, and often even clothing. I've seen it done many times. So why the whining? 
Morrow is right to get rid of loopholes if they result in a fairer tax system.
