FEATURE-Egyptians in Suez watch canal business and fume

* Suez earned Egypt almost $5 bln in 2010

* Protesters target businesses linked to Mubarak's party

SUEZ, Egypt, Jan 30 (Reuters) - When Hossam watches ships carrying the wealth of the world pass through the Suez Canal running alongside this industrial city, it fills him with frustration.

The canal, a vital trading route since the 19th century, earned Egypt nearly $5 billion in 2010, but the 33-year-old Hossam said he and others in the city where many are unemployed or struggling on paltry pay see none of the waterway's benefits.

In the past week, his anger -- and that of thousands in Suez like him -- boiled over into some of the most violent of the protests that have rocked Egypt and left President Hosni Mubarak teetering.

"The people are downtrodden," Hossam, a security worker for a paper company who did not want to give his second name, said.

"The richest province in the country is Suez. Where is its money? Where is the canal's revenue?"
