This video was posted by Ahad Abu Wadiya Al-Qa'actach, one of the most colorful figures in Gaza. 
He is well-known and was active in the "return marches", the riots on the border with Israel. He was present at every riot on the fence and considered to be one of the Gazan "influencers" on the net.

Abu Wadiya, who was previously detained by Hamas, addresses its senior officials and tells them: "Because of you, everyone wants to emigrate from Gaza." The video was filmed at the Rafah crossing with three of his friends who chose to immigrate to Turkey.

NEWSRAEL brings here the English translation (Share this video!!!!) :

Our youngsters are leaving Gaza, you leader!
Wake up already, you leader!
There are no young people left in Gaza!
Do you know why?
Because of YOU!
They are leaving to eat bread!
They are leaving to live in honor!
They are leaving in order to build a future for themselves!
That is what you ruined for them in Gaza!
These are our young people!
In the beautiful years of their lives, they are forced to migrate, to leave their parents,
To leave their society and those dear to them!
In order to build themselves a future!
Because of the chaos you brought, you leader!
You destroyed the youth in Gaza and left them with nothing!
Continue to fight among yourselves, for chairs and jobs and live there you and your children.
While you let our youth to live abroad.
In case they make it there in peace, or maybe the fish will eat them!
Say hello from us to your mother, you leader!
