This is more due to Bangladesh being a very low income country generally than anything else. It's not like Bangladesh was once the United States and devolved to its current state due to worker exploitation.

For most of the last century, Bangladesh was a basket case, unable to even feed its own people, and faced multiple terribly violent conflicts. It seems to have finally gotten moving over the last decade, and hopefully will keep on track.

We should definitely not "fear" such an impossible outcome.
