When the effective marginal tax rate is high, this is often as close as makes no difference, because you not only have the cost of bureaucracy but also the cost of working. You're paying an effective marginal tax rate of 80% so nominally you get to keep 20% of your income and have the incentive to work, but working requires you to commute, so you have to buy transit tickets or maintain a vehicle.
And because you're now spending your day working, you can't use that time to prepare food or maintain your household, so you may have to pay someone else to do some of those things -- but their entire compensation has to come out of the 20% of your pay you actually get to spend, so this can easily eat the entire thing and make you better off to not take the job.
