Adulthood

This is where you get to vote, smoke, drink, play the lottery, enter a casino, etc., The age was 18, but on January 1st, 2030, it was raised from 18 to 21, and the traditional college age range would be raised from 18-22 to 21-25 and 18-20 year olds would be considered minors and high schools would add "13th grade" for ages 18-19, "14th grade" for ages 19-20 and "15th grade" for ages 20-21. The extra grade levels will include a curriculum similar to a liberal arts degree in college and will include more essential 21st century skills such as critical thinking, communication,  environmental awareness, diversity,  technology skills, etc. These  skills will be important for entering a more globalized, increasingly diverse workplace and with dealing with the complex adult world.

Plans were originally to raise the age of adulthood in 1999 and to take effect on January 1st, 2000, but that never happened, then made a second attempt to take effect on January 1st, 2010 but that never happened either. A similar attempt take place in 2020 but never happened either.
