Here was a link to the US stats-
"The link between teen parenthood and a life of poverty
caught the American public’s attention in the 70’s when
the nation became concerned about the “epidemic” of
teenage pregnancy. The relationship between early parenthood
and family poverty is strong. National
KidsCount data show that, among young people who
delay pregnancy until they are 20 years of age, graduate
from high school, and are married, only 8 percent live in
poverty. However, of those who fail to meet these three
goals, 78 percent live below the poverty line."
Pretty much the same statistical outcome here you'd expect and we've come a long way from my folks' time where they couldn't even contemplate a society that paid you not to work, let alone subsidised teen pregnancy. Only married widows got support payments and most had lost breadwinners at war. You got pregnant without any means of support and either your family supported you or you adopted out, bearing in mind there was no sure way sheeting home paternity and support from that quarter.
A strict moral code and one that saw the moral majority want to rescue the half-caste offspring of what the 'good society' viewed as low moral white men taking advantage of poor aboriginal women, who almost universally became outcasts from their own culture as a result.
By the late 60s and early 70s my generation would pooh pooh all that and sweep it away with some unintended consequences and a rewrite of the history books. Such social change never occurs in a vacuum and with penicillin conquering STDs and the Pill, plus a remarkable period of post war prosperity, the social attitudinal change of a bulging youth demographic was fairly understandable. Interestingly enough the AIDS threat impacted such 'free love' thinking for a while until the threat abated but there is now some thought emerging a new threat from antibiotics resistant STDs may see a swing back again to the moral code of my parents' days.
In any case, despite all my generation's pooh poohing of our parents moral code, most of us followed their path to lifetime success more or less and we teach our kids the same.
