Isn’t the expectation of an employee in corporate America that they will eventually be able to apply to one of those “corner office jobs with a view” if they perform well and better themselves through more education in their field while working?

Although teachers don’t typically have such posh working conditions, why should it be any different for them, since they’re not less educated than corporate employees and often better educated? I think teachers deserve to have a clear ladder to better working conditions just like all other employees.
