Wrong

It is used pejorativly but that does not make it devoid of meaning

It refers to the social policies instituted in the 1980s that (attempted to) inserted competition into every facet of human relationships

It was instituted by liberals

It was new (and a dreadful policy that has lead to the discrediting of liberalism generally)

Hence "neo-liberal
