Before it falls to the archves

But the girl herself is the one who more often than not, would prefer to have fun (and learning in the way), instead of being charged with responsabilities, and is rarely mature enough to raise a kid into a rational human being.

I fully think the two are compatible. And even if they were a little contradictory, age segregation in all spheres of life worsens the situation. Prior to the industrial age, age segregation was unusual, and that provided for far more chances of mutual learning and for bestowing responsibilities upon the young in a more gradual, rational way. Even if they had a child "early".

Most single mothers are pretty careless about their children,

Not the ones I know - those are the most protective ones ever!

and live as parasites of the child's parent and the government.

I am ambivalent about child support. Too long a debate to indulge in now, hehehehe

And most criminals were raised by single mothers.

Ah, but also most criminals are black (USA).

The point being that the premise should be to punish people for what they did, not what they may do, or tendencies say they are likelier to do.

Well, that's what I meant by most workers.

Mh, no. The kind of workers I am referring to are only a significant number in the kind of poor but large countries that are going to most benefit from the changes.

The planet's resources are limited, and current growth is often linked to the deshumanization of less developed countries.

The planet's resources are limited, but we are not close to running them out, and we are learning ever better ways to use them without plundering them.

People are living longer, and most of the people in the world currently are living at extreme conditions, in China and India.

But better than they did even as little as 20 years ago.

'Underpopulation" is hardly a concern, specially since suicides (that happen often at asian countries due to cultural reasons), should be avoided as they reflect either immaturity or unhappiness, and true progress should actually decrease both in most population.

Aaaand Scandinavia!

My fave example of everything is that Sweden and Finland have more people killing themselves (%) than countries that are much less "liveable".

Umm, you failed the point there. And while it may be possible under certain circumstances, for a mother it's impossible to be fully dedicated to something of her interest or she'll be considered an awful human being.

OK that should change too. We don't say the same of fathers, yet fathers are in a similar predicament: some are good, some are bad, some manage to combine activities, some don't. Mothers too, and it's certainly not a crime to try to be both a mother and a professional at something.

Oh, I meant necessary for mankind's progress. We shouldn't think of our species as animals just looking for survival.

This deserves more talking too.

It's individuals who lead the world, statistics and social trends are useless when trying to view the big picture since society as a whole acts according to choices of individuals influenced by very specific morals.

Which is just why more young parents change the game ALL young parents play no matter which ones play it with more luck or success
