Do these actually help people?

Why don't you just know you're worth. The reason why you're not paid enough, is because you know you're worth more, but you accepted a position whose value for a good or service provided is lower than your potential.

Stop blaming your boss. Stop doubting your worth. Find a job that provides the most value that you're able to provide (not a cashier. Not a barista). And then get compensated according to that value.
