I see in my country many marriages at a young age and don't think about the economy in the future,
I know getting married at a young age is very beautiful,
but if the economy is insufficient, maybe should think again not to get married at a young age,
and I think from that marriage it can give birth to children and increase the population of the earth, and maybe in a few years the earth will be full of humans and surely there will be many other crimes to survive on this earth,
Is there a solution, to overcome this impending disaster
Not if the kids family is rich. There are people whose family are rich and they are free to do anything and when they get married their parents will be the one to sponsor everything and start up a big business for them. It can only lead to poverty when your parents are not well to do, lol.
Well, I wont advise anyone to get married at a young age, its best to go out and see the world, get the experience, open up a business or get a job and stop relying on anyone and get married when youre matured enough and sure that you can take care of your family.
