To "decenter [one's] self worth from [one's] job" would presumably require the fact that one's "access to basic rights is intermediated by a corporate job", no? This is a policy problem that needs to be solved by collective action, not a mindset problem that can be solved by personal growth
No you have to decenter yourself from your pay to achieve it. People accept things like cutting of medicaid because they see their job success as a moral success. There's a lot you can do to start being the good in the world that doesn't require Washington's permission.
