Who are the treacherous dealers?

Isaiah 24:16 From the uttermost part of the earth have we heard songs, even glory to the righteous. But I said, My leanness, my leanness, woe unto me! the treacherous dealers have dealt treacherously; yea, the treacherous dealers have dealt very treacherously.

If the blessed hope is very soon, then are there not treacherous dealers alive right now on the earth, in time of the tribulation?
