The WaPo and 'Slaves'

I sat there and tried to grasp this.....the Washington Post went and did a big research article over slavery existing in the world today (2020). 

Their facts.....near 30 million from around the world who are 'slaves' today.  The really guilty countries?  India, Pakistan, twenty counties of Africa, and to a lesser degree....Russia, Poland and several eastern European countries. 

Curiously, it then gives you the information that 60,000 slaves exist within the US.

The suggestion here is that various people were 'smuggled' into the US, with the idea of serving some master....for a debt of getting into the US. 

Looking over this definition....I'm almost agreeable to the 60k number but generally find this whole article lacking.  It should have told the whole US smuggling story in-depth, and how various characters are making this occur.  Adding to this....why is there no real police effort to undo this 'slave' problem if it does exist? 

One would think that Pelosi and McConnell would both be all hyped up and make some massive deal to undo slavery existing in the US.
