I don't know what your definition of corporate slave is, but you can certainly become wealthy off a salary.
Just limiting to software engineering (there's other lucrative fields out there) you can easily make a six-figure income remotely. This gives you the freedom to live somewhere with very low cost of living. It's not hard to build wealth this way.
You could debate that getting the necessary skills to get a job like this is harder than it should be.. that corporations themselves are broken.. whatever your worldview is that's fine but "cannot get wealthy off salary" is just plain false.
