CSR or GSR

Recently I was reading the editorial of 4P's which said that Corporate Social REsponsibility is sheer non-sense and that its actually Govt. Shirking REsponsibility (GSR ). They feel that a corporation earns profit and pays tax.Thats all about it. Social welfare is the work of Govt. which its trying to impose on the corporations. They seem to have a point. Is the government only for the sole purpose of propagating hatred among communities and corruption in the country. If they delegate their core tasks then what is the purpose of their enjoying the office? Govt. can not impose CSR on corporates. It is totally voluntary and an opportunity to earn profit and contribute to the society in a positive manner.
