Tenpenny Tower is a high-rise building in the middle of the wasteland, and is the nicest place in the game. Everyone else in the game resents the residents of Tenpenny because they’re all “rich”.
But what does that mean? Nobody in this game produces anything. Unlike in previous Fallout games, there are no farmers who eke out a miserable existence from the scorched earth. You can travel the entire wasteland in the game and not see a single farm, or garden, or anything else. (They have some cows, but it’s not clear what the cows eat.) Everyone just meanders about all day. People go to the bar at the end of the day and spend their money on booze, but the game never explains where they get their money, where their food comes from, or what they do for a living. (Or where the booze comes from, given the shortage of stills and raw materials.)
What makes the people of Tennpenny Towers “rich”? Their nice clothes? Their clean building? In that case, it’s pretty hard to feel angry at them. The rich people aren’t benefiting from ill-gotten gains from raiding, or slaves, or from cheating others. They’re just doing well. They do just as much work as everyone else in the world. (Zero.)
