I will be ranking all the playable races by how well off I think they are in terms of standard of living. Feel free to make adjustments, since I will be ranking them subjectively, if you feel a ranking is wrong, feel free to point it out. We’ll start out from worst and move up to the best. I suppose we could use real world standards as a baseline to compare, I don’t know what else to use.
Worst quality of life - Darkspear Trolls. Living standards appear to be very basic, very primitive technology, their magic styles negligibly make their lives better.
Poor quality of life - Forsaken. they live in tombs, underground cities, very unhygienic places, and seeing as how Forsaken can’t enjoy many luxuries (cant taste food for example) little resources get put into improving the quality of life. And this was before they lost everything in the 4th war.
Poor quality of life - Void Elves. When they left Silvermoon, they didn’t bring much with them. Spending most of your day fighting off the spooky voices in your head means you have little time for things like quality of life or luxuries. Probably classifies more as experimental weapons than a people.
Poor quality of life - Vuplera, a scavenger people with little resources or wealth, who live in a desert. Life is hard for them, though they endure.
Medium quality of life - Zandalari Trolls. They are more civilized, and seem to have more wealth than the Darkspear. The upper castes live in relative luxury.
Medium quality of life - Tauren. While they don’t partake of many luxuries, they do seem to be well off in terms of having their basic needs met. Mulgore is plentiful in resources, and many Tauren are skilled craftsmen.
Medium quality of life- Orcs. They seem to be industrious enough to etch them selves out a decent existence, though the warlike attitude means they put much of their resources toward war efforts rather than improving their quality of life.
Medium quality of life - Worgen. Gilnean worgen probably lost most, if not all of their wealth when Gilneas fell and they had to leave everything behind when they evacuated. However, thanks to the generosity of the night elves and of stormwind, Gilnean Worgen are able to live decently.
High quality of life - Dwarves, especially Ironforge ones. They seem to be an industrialized society, who put plenty of resources into good foods and beers. Ironforge is a very safe, cozy place to live.
High Quality of life - Stormwind humans. Humans seem to live well, Stormwinds economy is strong, its people productive. There is no shortages of food. But there is wealth inequality. The nobles live lives of extensive luxury, while commoners live mediocre lives.
*High quality of life - Night Elves. Their strong connection to nature through their druids allows them to readily have available food, timber, and many other resources. The average individual seems to live well. There is a form of aristocracy, but wealth inequality does not seem to be a problem. *(Since the burning of Teldrassil, and the night elves current state of a refugee population, they have slipped down to Medium quality of life. However, Stormwind seems to be helping keep them from slipping into poor quality of life category).
High Quality of life - Draenei. Very advanced technology, and a very spiritual people. Though technically a refugee population, their powerful technology, magic, and generosity toward each other allows them to live good lives.
High Quality of life - Gnomes. Also a refugee population, but again, extremely advanced technology and engineering skills lets them barter with the alliance in exchange for good pay and good lives. People go out of their way to hire gnomes when they need help with an engineering problem.
High quality of life - Goblins. Advanced tech, and a very commerce oriented people. While some of their number may live in slums the races combined wealth probably makes them the richest race on Azeroth. (Though there is extreme wealth inequality).
High quality of life - Blood Elves. Much wealth and magic seems to be put toward luxury in Silvermoon. Lavish wines and feasts are common. The Sunwell, a perpetual energy machine, can power virtually anything, making nearly any project far easier. As Highborne, they probably have large wealth inherited from their ancestors, especially the nobles.
High quality of life - Nightborne. Again, much resources put into lavish feasts and wine. Magic used to make life easier, and they appear to be a very wealthy people, perhaps even competing with the goblin race in terms of total wealth.
Highest quality of life - Pandaren. They aren’t the richest people, but they probably make the best foods and drinks, and live in balance, thus their society is probably very chill, and doesn’t have many of the problems others on this list have. Pandaria is a very bountiful land in terms of harvests and resources. They may not be able to get every luxury they want, but they probably live the happiest lives of anyone on this list.
