Prior to school it would allow parents to pay for daycare, diapers, food and subsidize paternity/maternity leave.
An 18 year old these days is still a child. Give them a couple years into the drinking age to get their bad decisions out of the way.
It is my opinion that this huge collective distrust towards youth is one of the biggest hidden problems of today's society. If it was up to me, kids would get a basic income from the age of 14.
It's not the children's fault, either. It's just a fact of the times. More schooling is required than before, and continuous schooling shelters people from having to make many real world decisions. It's easy to live a "don't care" lifestyle during college, only to be hit with reality hard once you graduate. I've personally experienced this.
There is a major difference in meltalities of someone who's been in school their entire life and someone who's been in the "real world" for a few years.
I'm not sure of your age, nor am I suggesting that it would have any negative impact on your perception here, but we seem to have different perceptions of the youth of today. I am 25 years old and I can only speak on my experiences.
And my experience shows that there's not much of a difference in maturity between an 18 year old senior in High School and a 22 year old Junior in college.
However, there's a huge difference between a 22 year old Junior in college and a 24 year old who's been working for a year.
In the end all society's have a baby-elder process with many stages. We let 15 year old's risk their and others lives driving multi thousand pound vehicles at 70+MPH. We keep prescription medication behind many additional hoops even for well educated 60 year old's.
IMO, the real difference is how much education people need. A 15 year old can dig a ditch just fine, but cancer research takes quite a bit more. In the end society simply values 15 year old's time less.
Don't stereotype.
I don't see what's wrong with my stereotype in this case. Most people under 25 are not financially independent, and it's mainly due to the society we live in, not the children themselves.
When my Dad was growing up, people had full time jobs at 16 years old and were married with kids by 25, where as today, the average person doesn't even graduate college before 23.
I'm not blaming the children for that.
An outlier can't be treated like the center of a distribution. Your own experiences don't mean that most 18 year olds aren't still children. It's not like the government is going to start maturity-testing people to decide when to start dispensing a basic income. They're more likely to test a "representative population" and set the age to the point where 2/3 test as "adult", or use one of the traditional age-cutoffs like 18, 21, or 25.
My main point is that a few years should go by after a child enters into the adult world before they have access to a fund left for them.
There's usually a short "reckless" period immediately after graduating high school and college. However, this usually calms down after the initial shock of having sudden freedom wears off.
I have two friends who inhereted $20,000+ sums of money from relatives when they were in their late teens, and both of them pissed it away in under a year. Looking back, both of them seem to regret it.
(Me and my friends are all around 25 years old).
