Who exactly do this lot think are going to be looking after them in hospitals and care homes when they're elderly and infirm?
If only those who could really afford to have kids had them - a decreasing well-off demographic -we'd be even more fucked than we already are.
Immigration is not a long-term solution when 80% of elderly are going to be spread across low and middle-affluent countries by 2050, either. Every country is going to need their own citizens.
Instead of resenting people who need their wages topped-up by the government in order to afford having a couple of kids - maybe embrace those who are making sacrifices to have kids at all, especially in the face of the overwhelming decrease in value that society and successive governments have placed on the role of raising children.
