I think many of us here don't get paid by W2 or by 1099. We are compensated in different ways which don't require those types of filings (e.g. K1), in which case we do need to fill out forms.
The portion of that cohort that file 1040 (generally those that make over 100K and have situations that make itemized filing more efficient than taking standard deductions) is pretty small.
You were outraged at hedge fund managers classifying their income as interest (15% tax) rather than "earned income" (~35% income tax)? Well, wait until the income tax goes back up to 50+%, and see how many non-"earned income" ways there are to compensate employees...
