"Decent living" doesn't mean that you're under or overpaid for your skill set, position and responsibilities. It usually means based on your geographic area as a whole (or objectively whether or not you can sustain yourself).
The median household income in the US is a "decent living" in almost the entire country, even some urban centers. Saying that 2x+ is a "decent living" is completely tone deaf.
Depends on where you live. In SV, sure, but they have the highest cost of living in the world.
In Dallas, a fresh out of college CS grad can probably expect a salary in the lower 40s. And the cost of living is cheap enough you can afford a house on that.
Really? That seems weirdly low, even with a lower COL taken into a account. In Southeast Michigan a new grad would expect to start somewhere around 60, and that's enough to buy a decent to huge house depending on where you end up living.
That's a sad salary. Especially when moving a few hours away to San Antonio will yield a 20k+/yr salary increase. Even if housing in Dallas were free, it's still better to move from a financial perspective.
It's over double the average family income in the USA.
