This social trend along with others which are undesirable and rare in society before the 1960s, such as increased rates of family breakdown and increased rates of abortion, all have their origins in something called “social Marxism”. This in turn originates from the Marxists turning their attention to social policy to gain greater control for the State, because the traditional Marxist theories were failing. A key element in this movement was the Frankfurt school, started in Frankfurt, Germany by old school socialists and psychologists joining forces.
Essentially, the direction of travel of policy which does not incentivise marriage is due to the theory that stable families are a barrier to greater state control. The State is seeking greater control and power over people’s lives, and it was determined certainly in the Frankfurt school that this needed to be attacked and attacked aggressively.
Traditional marriage is the bedrock of the family and this is why it was the target of government policy to make it only possible financially in the romantic sense for the richest in society. Removing all financial incentives and in fact incentivising single mothers and mothers to pretend to be single, if from a poorer background, is all part of the plan I am afraid.
It’s an extremely cynical social engineering project and this is why, as the authors point out, the financial costs to the State are accepted in exchange for the benefits this brings to the State in terms of having a greater amount of power and influence over more of people’s lives.
