From the IEA’s promotional text:
enhanced freedom with respect to family choices that has characterised the modern family and is celebrated by those on the political left, is largely a product of the economic system, market capitalism, which they often reject. At the same time, those on the right who are troubled by these changes in the family, including the demand for same-sex marriage, need to realise that such cultural changes are an inevitable by-product of the economic freedom they claim to celebrate.
Steven will argue it is capitalism that is the main driver of the evolution of the western family and the wider array of family structures, which characterises the 21st century, representing an increased cultural freedom brought on by the freedom to engage in capitalist acts between consenting adults and the wealth it brings in its wake.
Gay marriage, single parenthood, granny living separately are all things that require money to make happen. A traditional family home in under-developed India, for example, contains two generations including upto four bread winners, but the potential for extreme pressure to fall upon the shoulders of the oldest son, who shoulders the burden of being a financial safety net for both generations. This is changing and the blame for that is placed on the westernisation of their culture, but maybe India’s new found prosperity plays a stronger role?
