In simplistic terms a pension relies on the continued growth of the entity that funds it so we can ignore our political biases and just look at the math to test the truthiness of your assertions: an entity with stagnant income simply cannot continue to fund a growing population of retirees. Historically, very few corporations outlive their employees [1], so pensions aren't a good fit for the private sector. Governments rely on growing populations to fund their pensions, and with negative population growth in so many areas of the country these days they seem hard to justify in the public sector too.
