The senior politicians make less money than celebrities in some country. One of the reason may be that people know famous people better than those who make important political decisions. I believe that the drawbacks outweigh the benefits.
A reason why people such as actors and musicions can make revenue more than govermental people is that they spend considerable time on social media and TV programs. as a consequence, public crowds might get to know them more. If so, companies tend to pay money to them on producing an advertisement. In other words, the more people know a person, the more they trust to products they promote. As a result, firms seem to prefer to spend a lot of money to celebrities than political scientists who have no spectator. So, the former group earns higher salary.
Many people consider this trend as a negetive. This cause the young attract to art jobs. They like to have a fortune and tend to buy properties like cutting-adge equipment, a modern house, and a unique car. This lead few number of the celeverest people study to be a politician, which is a job to develop a country and make life easier for people.
To sum up, I think that business markrt invest in advertising can cause popular people earn more incom. In-long term, countries with this development may face large setbacks. There is a less chance that their managers be from the intelligent people. So it cause the government cannot make good decision in critical moments.
