The three million Moroccans living abroad represent around 10 per cent of the country's resident population and their money transfers are its biggest foreign currency source after tourism.
An official report early this year said Morocco must create 400,000 jobs annually over the next 10 years to prevent mass unemployment, especially among graduates.
The government is turning to expatriates to help build the businesses that will create those jobs.
But many of those who fled unemployment in Morocco now have good jobs, higher living standards and foreign-educated children.
Even those struggling in the European job market who feel discriminated against because of their origins say a return to Morocco holds risks and uncertain rewards.
"It's already hard enough getting by in France," said Jaouad Ouargo, a 21-year-old auto engineer from Paris, as he queued in the northern port of Tangier for the ferry to Spain. "If I try something new here, it'll be harder."
The government is trying to boost sluggish economic growth by enacting investment-friendly reforms and making the banking sector more robust to cut lending rates.
High-value industrial exports are being nurtured with free trade deals and heavy transport infrastructure investment to reduce the economy's reliance on drought-prone agricultural.
While foreign investment in Morocco is booming, spurred on by large-scale tourism and property developments, expatriates appear loath to sink their money into smaller, job-creating enterprises.
A return to Morocco for many
holds risks and uncertain rewards
Some $2.58 billion were repatriated in the first half of 2006, 24 per cent more than a year earlier, but most went to support families and build second homes.
Many Moroccans living abroad say they are put off starting a business by complex administrative procedures, the risk of long delays in getting the right documents, and a perception that you need powerful contacts in business and government.
"This reticence is linked to a totally outdated image," said Jelloul Samsseme, head of Morocco's northern regional investment centre, saying anyone wanting to start up a business could have all the documents they need from one location within 48 hours.
"We hope to establish new instruments ... including an investment fund"
Minister for Moroccans living abroad
At annual meet-and-greet events to coincide with the summer exodus to the motherland, officials try to convince Moroccans based abroad that setting up shop at home has never been easier.
Procedures are far simpler, interest rates have fallen and the state offers tax breaks and help buying land.
Nezha Chekrouni, the minister for Moroccans living abroad, said: "Yes, there are still many problems but we are doing our best to solve them.
"We hope to establish new instruments ... including an investment fund."
Tough for children
Kamal Lahsen, 35, grows lettuce in Spain and says he is ready to come home. It would be tough for his children who speak only Spanish, but he wants to be near his family.
"It's got easier to create a company and I think I could get financial help," he said. "Next year I'll try to get some money together and then - who knows?"
Builder Jawad, 35, remains to be convinced.
"My father had a business here building shop interiors but he went bankrupt and the reason was corruption," he said.
"In Morocco you have to pay lots of money to win new business and he was behind paying his workers and lacked the cash."
