I'd assume that "returned home" is doing a lot of heavy lifting here

Unfortunately a lot of countries only want educated/skilled migrants and those able to work. Which is perhaps unsurprising given the current economic outlook. Some countries even skilled/working migration numbers are being reduced due to housing and plain old racism.

A lot of these migrants specifically lack skills to be able to contribute or effectively integrate in their desired destination. It is what it is, which is more depressing given a lots of countries that these migrants are emigrating from were fleeced of their natural resources for years and kept intentionally in various states of conflict and poverty to facilitate this. IOM sounds like it’s squandering money and failing to provide meaningful migration pathways. Which is incredibly unsurprising.

Folks like to talk about the Trump immigration hysteria as a uniquely American phenomenon. But this rampant racist xenophobia is an epidemic plaguing the entire NATO block.
