WE have some wierd fetish with letting kids be kids for as long as possible. Sorry but at 13 you are biologically an adult so you need to have adult responsibilities and adult expectations. these teenagers need to get off their asses and work, build, etc.. Instead we extend this out to age 20 before we expect them to get a job and start being responsible.
Less than 100 years ago it was not uncommon for marriage at age 16 and that young couple working hard to build their family Average age of a woman getting married was around 21 years of age. Today it is far higher at 26 years of age and insanely uncommon for a 16 year old marriage, Although outside the USA it is far lower. Mexico has a median for women at around 18 years old. Many states in the USA still have the age of consent at age 16. This means that 16 year olds can make decisions as an adult, yet for some reason we think they cant today and are still children.
Note on marriage ages, some of this is economics, back 100 years ago it was a lot easier to make a living as you made about $35.00 a month working at a foundry or smelter and typically renting a house is $5.00 a month less that 20% of your income was your rent. today most of the young pay 60% of their income as rent and have to split that rent with room mates because they can not even hope to even meet rent with their meager income. So 100 years ago it was easier for young and uneducated to make it in the world with the sweat of their brow.
