Why can't young people save money now?

My mom: How much is your monthly salary now?
Me: Just over 7k
My mom: If it's 7k, then you can save 84,000 a year
Me: ?
My mom: Isn't that right?

Me: I still have rent to pay
My mom: Then your rent for a year is only about two thousand, right?
Me: ?

My mom: How much is that?
Me: 1300 a month
My mom: You're living so expensively, can't you find a place for two or three hundred?
Me: ?

My mom: Are there any other expenses?
Me: The money I spend on food I borrow from colleagues and don't pay back,
Medical bills are directly extorted from hospitals,
The money I give you every month,
And the money I usually spend on clothes are all blown in the wind,
Oh, and the car and fuel are stolen,
I don't even make friends,
And for dating, I only look for aunties who can give me money to spend,
All in all, I can save over 100,000 a year.
