Why can Putin destroy oligarchs, but the South Korean president can't suppress the chaebol?

Some people in Russia are called "oligarchs". Oligarch appeared because of the disintegration of the Soviet Union. Since the disintegration of the Soviet Union, many military industries have been inherited by these oligarchs. They not only inherited the economies of these countries, but also completely controlled the oil, banking and even news departments of the country. Because of this monopoly in Russia, oligarchs have a decisive position.

This status of oligarchs has also seriously affected the Russian presidential election and official appointment, and many officials rely on the support of oligarchs. But after Putin came to power, he took oligarchy to build the national economy. He sent the former richest man in Russia to prison, and naturally returned the national heritage of those former richest men to the country. In this way, wealth will be owned by the state, and Russia's wealth will be improved. After these industries return to the country, the normal operation of securities and stocks will not be affected, and there will be no side effects on the country.

Similarly, there are some economic chaebols in South Korea that control the country's economic lifeline, and their enterprises are particularly huge, affecting the national economic income as high as 5%. Moreover, these enterprises are private property, not inherited from the state, and the state has no right to control these chaebol. Moreover, politicians hope that the country's economy will develop well and the people will live a happy and prosperous life, so Korean political circles rely heavily on these huge chaebol.

There is almost such a political concept in South Korea, that is, "changing the president cannot overthrow the chaebol." It can be seen that in South Korea, presidents can change one after another, but these chaebol must let them live, because they control the economic lifeline of the whole country. However, these chaebol in South Korea will never interfere in South Korea's politics, let alone despise the authority of the president, so they will not be hated by political circles, and they will not have the idea of suppressing chaebol.
