When they reduced corporate tax about a decade ago, they argued that businesses would reinvest their profits and increase employment. The conglomerates did not neither. In fact, they reduced employment and investment. They promised many times to increase employment and investment, but did not.

Another critical article typical of Korean media blaming increased minimum wage and critical of the Moon administration. Most Korean media do not seem to want a progressive government to win in the next National Assembly and Presidential elections. The conservative party's popularity is at an all time low, yet they have yet to mention this in the news.

Korea is still run by the conglomerates and the wealthy, at the expense of the people.
