People want to live near evisting jobs so your someplace new will be a suburb and generally has constraints because of that. You have to get people into the city for example which forces car dependance for example.
Would you like to be the first and start a new city? Would you move to the middle of, say, South Dakota and start New New York City? If it’s as simple as you say, in a few generations your new city, lotsoweiners, will be getting the jobs.
We can look at mining towns to see projected growth. Mining towns have to start where the ore is, and they generally can pay a lot more than average to attract people. However such towns tend to die when the mine closes unless there is some other reason for the town to exist. That other reason is not how nice the town is, but geography. Note that I said town above not city.
Cities exist for geographical reasons, if you don't have the great port (either ocean or river) to attract people 300 years ago to settle there you won't get people today.
