That's a bit disingenuous, trying to invoke a blue vs. white collar dichotomy where none exists. Many office workers have equipment to lug around regularly, and many more types of people than office workers would be taking transit.
Regardless, transit should pay for itself in the same proportion that roads pay for themselves. Transit has per-use or per-distance fees around using it, but are also subsidized by the government. Road travel has per-use or per-distance fees (tolls, gasoline taxes), and are also subsidized by the government. I'm sure we can continue to find a balance for all of those numbers so no one is disproportionately burdened to support their needed mode of transportation.
