Recently, companies are very interested in ESG. What is ESG? E is environment, S is social, and G is governance. Especially, large companies have been thinking about social responsibility. They pursue profitablity in the past, but now, they're pursuing profit and public interest. It is also called 'Cause Marketing'. However, small companies can't afford that. Startup companies can't, either. ESG is badly needed in achieving 'balanced national development'. Because the gap between the highly-educated and the low-educated. In perspective, the gap can be narrowed. In the end, because, in a capitalist country, polarization deepens, co-existence is necessary, and a change in social structure is needed. In addition, ESG is being justified. According to a news report, big firms, like Samsung , LG and SK, are joining ESG now. In conclusion, due to covid, everyone is in a hard time now. But everyone is trying to overcome the ongoing crisis everywhere in our society!
