That is where the bulk of tech jobs are, around cities where you can make that much. For example, you can make that in Seattle or basically anywhere in the bay area (no, you don't need to live in SF unless you want to). The cost of living is higher, but the cost of living in large EU cities where tech jobs are going to be is similarly higher. I think people also make bad comparisons when doing cost of living exercises. While it is true that potentially much more $$ will be going to rent/mortgage in a high cost of living area, many other things are going to be the same as anywhere else. A $100k Tesla is $100k in SF just like its $100k in North Dakota. After tax + basic needs costs and someone in a large tech city is going to have significantly more disposable income still than someone making much lower salary with much lower cost of living.
