Undervalued and Overvalued Occupations

I was shocked to find that civil servant salaries are lower than I thought.
Hairdressers earn more than expected.
When I asked painters and tilers while doing interior work, their income was quite high.
People say oriental medicine doctors and lawyers are "dead" (struggling),
but all the truly wealthy people around me are doctors, oriental medicine doctors, or lawyers.
Entrepreneurs live large and may do well for a time,
but there are rarely any with long-term stability.
Self-employment is even more serious.
There is a lot of exaggeration.
