Unless their personal time is worthless, it's functionally the same thing as lowering their wages, and contracting out to an accountant. Except that an accountant would probably do it faster and cheaper.
In another sub-thread, you said that this should be automated, and that nobody should have to do this busywork. I strongly agree. That's not the world we live in, though. As of today, somebody has to do this busywork - and when that somebody is an expert, they can probably do it a lot better then I can.
