"Social responsibility" produces a better overall society? How? By encouraging a lack of personal/moral responsibility? By legitimizing theft? By acclimating people to expect copious benefits without having to pay for or otherwise earn them?

As for who manufactured the scam, you hit the nail on the head. There are those who are in power and wish to remain so, and the best way to do it is through bribery by theft, aka welfare/"social responsibility". It's not a conspiracy to hurt themselves (laws are for others, not them), but to gain control over others. It's just like giving wild animals food; soon they lose the desire and incentive to hunt/forage for themselves, and you've gained control over them.

Before you accuse me of "gross generalizations", you should know I was born into a dirt poor family. But we had pride, morals and a strong work ethic, and my parents were proud to have never taken welfare. We knew the welfare people and wanted nothing to do with them. Many had kids just so they could collect more welfare per child and proceeded to spend it on alcohol, cigarettes, gambling. Essentially whatever the parent(s) wanted, the kids be damned with most of them turning out bad--prison, murdered, or a second generation on welfare. The theme has continued throughout my adult life, only it's now extending into the middle class as well.

Finally, if you think my "gross generalizations" from personal experience and observations are repulsive, I know people who have a much harder stance on this topic than I do. They're a friend of mine and her colleagues--who are social workers in a major US city. She (and perhaps the others) got into the field to help others get back on their feet--only to find not apathy but hostility towards any attempt to get them off "social responsibility" programs, sometimes to the point where she's felt her life in danger.

A better overall society indeed.

"Social responsibility" produces a better overall society? How? By (hopefully) raising the lowest members of society out of poverty and poor education. Society here meaning "the group", not touching on any sense of morals.

Assuming that your "social responsibility" taxes are only intended for poor unwed mothers is a gross generalization regardless of your personal background.

Being an mother (or father?) is not traditionally a career choice. If the state wants to set up a formal program for people to get paid to have children, it should do that. A system that gives a financial incentive to having children can and will be abused.

Do you have any numbers that actually suggest poor parents are profiting off of such programs? Children are, strictly financially speaking, a huge expense.

Look into the marginal cost of raising a child. Children are a bigger expense for upper-middle class people who expect to send their children to a private school, pay for them to go to an expensive college, want each kid to have their own room, etc. For poorer families the main expense of a child is food. The younger ones can wear hand me downs, it is possible to shove two or three children in one room, etc. The poorer the family is, the less having another kid costs until it is actually a negative cost because each additional child actually brings in income by working.

What incentive is given in systems like Hungary's? Are you saying that such lengthy parental leave is an incentive to produce babies? This would seem to ignore all of the other impacts of having a child on your money and time.
