Supposedly IQ is going up for college grads, but from what I can see the long-term trend can't be good.
It's now been proven that smart people tend to have smart kids, and if you have a high IQ you're generally going to do well in life because that's what our free-market, capitalist economy is set up to recognise. If we define success as being relatively wealthy and useful to society then proficiency, industriousness, organisational skills, communication, foresight and a good grasp of STEM are what counts. Unfortunately though, these people also tend to have fewer children.
As an example, I would consider most of my mates to be successful (the jammy f#ers). From my 7-10 close mates they all have a mortgage, they all drive, they're all married or in long-term relationships and they all have responsible jobs. They also only have 1-2 children.
Now, on the other side there's the people I'd prefer not to know. There are at least as many dolies, professionally unemployed and general waste-of-space people that I have contact with. The problem is, the fathers are absent and sometimes petty criminals or druggies and the mothers have multiple children because, in spite of being young and pretty, they choose to breed with retards and losers. They then find themselves with multiple children of different fathers and unable to cope. These children often portray the feral behaviour of their parents and so the cycle continues.
Ergo, responsible people have fewer children, whereas all the impulsive, idiotic and irresponsible idiots have multiple brats because they're stupid and incapable of long-term planning. You only need to read the criminal news in the local rag to see most of the scum have a plethora of illegitimates by the age of 19 and have no intention or means of ever supporting them.
I realise I'm coming across as a bit einsatzkommando here, but if we carry on like this what will be the future of our society? It doesn't help that we're also importing a load of economic migrants who have no useful skills or qualifications and often make the situation worse.
Would we be better off under a benevolent dictator like Putin who could put in a bit of population control, or is our own freedom and individual liberty (the right to be idiotic) going to be our downfall? You can probably see this theory in reality when you observe sink hole estates and ghetto cities such as Detroit.
