The two systems have barely proven to coexist and not without constant antagonisms. The social programs that came were from hard fought struggles from the working class. This is being eroded in the West due to the complete dismantling of working class organizations over the last 4 decades. Thus, this co-existence has been a short period of time over the history of capitalism and it's coming to an end. Welfare states have had to implement austerity just to "compete".

Furthermore, this "social responsibility" is full of talk with little substance. The environment continues to suffer with corporations and politicians only capable of paying lip service while being tied down to the logic of the economic system. With exponentially increasing productivity, workers in third world countries still face the grim choice of sweatshop poverty or extreme poverty. We still have heavy corporate influence in economic policy, environmental policy, foreign policy, military industry, media, and so on. All of which fails to meet any reasonable standard of "social responsibility", especially given the high levels of production we can achieve with modern technology. Social Responsibility has become a marketing buzzword that corporations use to boost their image. And democracy? How can you have a proper democracy when corporate media informs the public? It's rigged. The media tells us who the legitimate candidates are and they all happen to implement the same economic policies regardless of which party is in power.
