With a literal servant class that does all the actual work, no less.
The reality is there isn't a "left" in Tolkien, even under the original definition from the French Revolution, it's monarchism all the way down because at the end of the day he was a pretty firm monarchist making a pseudo-Catholic fantasy setting.
Hear me out. Dwarves are actually communists and not serfs in an absolute primogeniture monarchy. Here is how and why: Once the dwarven guilds/unions had distributed the wealth produced by dwarven labour evenly among the dwarves, they realized they were already in a post scarcity utopia. Now, they started diggy digging just for fun and named one person king as a joke so they had an excuse to forge exquisite regalia, coins and other stuff. At some point they just started putting it in a hole so they could make space for new creations.
Yes, it's common in most English speaking countries, but Samwise is literally an employee of the Shire Baggins.
The Gamgees are of a lower social class than the Baggins. Samwise' father, The Old Gaffer, also worked at Bag End. Frodo has generational wealth, not just from Bilbos adventure with the Dragon, but his Mother was well-to-do also. Bilbo and Frodo had servants, groundskeepers, and housekeepers. That doesn't even include the party staff they hired on.
He also calls himself "your Sam", and Frodo is called his master even when the narrator is speaking:
he had stuck to his master all the way; that was what he had chiefly come for, and he would still stick to him. His master would not go to Mordor alone.
It’s still used (even in the US) by older people for boys not yet of age. My grandma, who died in 2009 and would have been 103 this April, would send me birthday cards addressed to “Master [root_beer]” when I was a kid.
