Rent is sort of surplus gained due to advantage of scarcity rather than advantage of production. Unfortunately, I cannot write a HN comment that differentiates more clearly but that's the rough idea. Like setting up a guild and saying no one can do work except through the guild and then using that advantage of pricing is rent-seeking. Just being better at doing work so you make more money is profiting.
