In my market, a major city in the US with a reasonable cost of living (ie a five bedroom/3000 square foot house in a good neighborhood in the burbs can be bought for $350K), the average framework developer who can push out a CRUD REST API in Node and can throw together a website with Bootstrap and React can make about $120K in a few years out of college and live a nice comfortable life and is well above the median income - I don’t think that’s doing too badly and certainly not “low expectations” based on salary.
