Mr. Speaker, that is a ridiculous question, especially from a party that claims to believe in evidence-based policy. Here is the evidence: we have an aging population; the number of workers and contributors is diminishing considerably; and the number of beneficiaries of programs like old age security is growing. As a result, we need to protect today's pensioners and make responsible changes, as virtually all other industrialized countries have done.
