This is seriously, seriously wrong.
Why on earth would someone spend the effort to be a lawyer if they just get paid the same? How do you think exceptional employees would feel about carrying everyone else like that? Everyone's going to be HAPPY to be a carbon copy cog in the great machine? If everyone has the same disposable incomes... people would be fighting for the easy jobs. The unhappiness has only moved from feeling taken advantage of due to differences in wages to feeling taken advantage of due to the vast differences in job difficulty across the entire company's payroll for the same disposable income. )".
Maybe, if pay was the same, people would actually be able to focus on doing the jobs that they ENJOY, instead of feeling like they had to take a different position to afford to eat. This has the added benefit of the fact that people who are doing jobs they enjoy/care about tend to do better at those jobs and try harder, so the company better results as well. Bottom line, some people enjoy the work of lawyers, they would still go through the trouble to become lawters. Other people enjoy managing, they would still take the time to be managers. Some people enjoy being janitors, they would feel free to do that without feeling like they were missing out on a paycheck.
Regardless of whether a mission expands or contracts, administrative overhead continues to grow at a steady rate.
