You can consistently get $100k in Silicon Valley, New York City, and Washington DC Metro, although you will need Top Secret security clearance for the latter.
It should come as no surprise that the expenses in those areas are much higher. If you settle for a lower salary in an area with lower living expenses, your effective savings rate could be higher.
Also, you don't want those DC jobs. Just say no. The military industrial complex is a soul-eating machine, and it does not respect software professionals.
The problem is that other places have fewer available jobs in the field, and a greater proportion of them are extremely unglamorous. $90k maintaining a stupid, business-line CRUD app may be less attractive than $80k making custom software for medical researchers.
