Anger is a great business, people will share it with you for free and if you're savvy enough, you can sell it back to them. The Rage Mages descended from Belligerus's early followers have found that modern world has just as much use for anger and magic as the ancient world.
In some regions, various occupations might be exclusively staffed by members of a particular race or ethnic group. As examples, a city's butchers might tradtionally have orcish blood, or all the dwarves in an area could be expected to join the miners' guild (even if they personally have nothing to do with mining). Those who violate these stereotypes may find themselves in conflict with local customs or idiosyncratic laws.
