Merging Port Authorities? Busan will suffer the most ㅠㅠ

First, if you compare the revenue of the four port authorities:
Busan Port Authority: 400 billion KRW
Yeosu Gwangyang: 150 billion KRW
Incheon: 150 billion KRW
Ulsan: 110 billion KRW
Unless the integrated headquarters is located in Busan, Busan will suffer the most ㅠ
People in Busan extremely dislike leaving the city, so if these regions turn into branch offices and staff are rotated nationwide, Busan will be the biggest loser.
