although economics of hobbiton doesn’t make goddamn sense anyway, samwise is hereditary gardener/butler
We weren't shown really much, but it does make sense, Bilbo and Frodo are local gentry kulaks that did not worked a day in their lives, but we weren't show people who labour for them, except Sam who is literally a house slave. Merry and Pippin were failsons of the kulak clans who each fatten up on a good portion of Shire. Between the names of Baggins, Took and Brandybuck they had so much power in Shire that they did whatever they wanted there.
