I do believe that scientific research is beneficial to the common man because it can help to find new ways to improve health and ways of living. It can promote growth within the human mind and also find healthier ways to live for people that may be suffering from certain diseases.
Scientific research is beneficial to everyone including the common man. Not every scientific discovery is going to apply to everyone but you never know which ones actually will. Diseases such as cancer touch every economic level. A cure would benefit everyone. Scientific research needs to continue to benefit us all.
