Why are men useless in today's world ?

I don't think they are useless at all hun.

We are not useless. It's men that primarily keep society up and running. We are primarily the ones that build things. We are primarily the ones that maintain society's infrastructure. We are primarily the ones that design the things that make life too easy for people and especially so for women. How many women do you see working in the trades? How many women do you see doing construction? How many women do you see doing road work? Engineers of all types are primarily men. If women were in charge then we would still be living in grass huts.

Speak for yourself and men apart of the generations Z. Men sustain society. 

It would be interesting to see how long women lasted without men to provide for them.

The home they live in.

The car they drive.

The roads the car drives on.

The Internet and cell phones.

All utilities.

All provided by men.

men keep the world going
