To be fair, the original topic of this thread was "tax traps", one of the most famous in the UK being a gradual decrease of benefit that was still a marginal increase in net, but it was still deemed worth complaining about.
Yeah, to some extent it's also important that the marginal tax rate should always be monotonically nondecreasing. But that's not quite as critical as the marginal tax rate never being above 100% (including all accounting for loss of credits/deductions).
