There's no class,
There's no middle class, no rich class and no poor class.
You can't say in which of these classes you lie because your class depends upon how you see your life after 5 years or 10 years.
Might be possible you are earning 10 times more in next 10 years,
And then 10 times more after those 10 years.
So you can't say about your class.
It's just sometimes you are having bad days and sometimes you are having good days.
But that span of time can't decide your class.
