Given that the largest source of man-made debris is Chinese, I don't see that happening.

Why would I pay a cleaning company instead of spending a lot less money on moving the satellite into a graveyard orbit before it runs out of propellant?

Because accidents will start to become more common, and the more stuff we keep putting up there, more often they will occur.

or don't, and leave it there?

You'll be sued for domino effect that crashed everything?

But seriously, I have no idea how cleaning operations will look like. There are tens of thousands small piecies flying around at high speed. Every time I think about it my brain gives back cartoon scenes only as solution to cleanups.
