One might consider that adulthood takes place when they are cast into the world with no safety net. If so, adulthood can happen at different times. I think that in America the vast majority of people could be said to be lacking adulthood until their 30s at least. Its very easy to have a different perception of what is important and what is not given what you are required to do daily to survive.
Is it the casting out into the world without a safety net that makes someone an adult or is it the changes that occur in a person as a result of that?
Because not all that are cast out thrive...some drown
So what is adulthood in modern western society?
In previous civilisations it was marked by rites of passage
Nowadays could it be said to be the point where a person is able to stand on their own feet in every sense?
If so then what implications does the housing bubble and the pricing out of first time buyers from the market have on the ability of young adults to stand on their own two feet in economic terms?
Previous generations also had a 'job for life' but nowadays young people live a more insecure life of 'portfolio careers' where they jump from one job to the next often competing with cheap foreing labour for jobs (here in the UK highly skilled workers have piled in from countries whose economies have been ruined or don't offer great oppotunities like spain, poland, italy etc)
The decline in the purchasing power of the currency also threatens the ability of young folk to pay their own way in the world
Because the politicians have raided the pensions pot to give tax breaks to their rich buddies the young now look at a future where they will not be given a pension and will have to work until they are brown bread (the 'age of austerity')
