Briant Whitaker has been doing an extraordinary job covering the story of hundreds of thousands of expatriate workers expelled from Saudi Arabia due to a change in labour laws there. You can check out all his posts here. Recently he explained why he thinks this is such an important story:

For the last month or so, as regular readers will know, I have been following the story of Saudi Arabia's crackdown on migrants. I have spent hours gathering information from open sources in an effort to get a clear picture of what is happening – and this is my fourteenth blog post on the subject in the space of four weeks.

To some this might seem excessive or even obsessive but it's an important story that international media – and especially western media – have largely failed to notice.

It's a story that deeply affects the lives of hundreds of thousands of people, mostly from the world's poorer countries, who have been living and working in the kingdom – as well as countless relatives back home who have been depending on their remittances.

It's a story that heralds fundamental social and economic changes in Saudi Arabia itself, possibly leading to political changes too.

It's a story that also affects other Arab Gulf states, since they have all become heavily dependent on foreign labour – basically relying on those they regard as inferior beings to do dirty, menial or dangerous tasks from constructing their buildings, driving their cars, cooking their meals, cleaning up their mess and preparing their dead for burial. Many of these people work in conditions that amount to modern-day slavery.
