By PETER ORSIHAVANA (AP) â¿¿ President Raul Castro declared Thursday that Cuba's two-year experiment with market reforms is working and has the wind at its back, but said much work remains to breathe life into the sputtering economy. In a speech devoid of any new policy announcements, the military khaki-clad leader sounded a generally positive tone in discussing the Marxist country's progress, though he conceded that the island faces a "colossal psychological barrier" in shedding old habits and "concepts of the past." "The updating of the Cuban economic model ... marches with a sure step and is beginning to delve into questions of greater reach, complexity and depth," Castro said, according to an official transcript of his remarks before lawmakers at the second of their twice-annual sessions. The proceedings were closed to foreign journalists, but state television later broadcast tape-delayed highlights. Cuban economy czar Marino Murillo told the assembly that the government is planning more measures to support and increase the ranks of independent workers and small business owners. Real estate broker, delivery person, antiques dealer and produce vendor will all be newly legalized private jobs in a country where the government has long dominated the economy and employed nearly the entire workforce. The self-employed "are gaining space," Murillo was quoted as saying by the Cuban news agency Prensa Latina. Economists have said Cuba needs to expand the number of allowable private enterprises, with an emphasis on white-collar work. Real estate has been a particular concern. Cuba legalized the buying and selling of property 12 months ago, but has yet to allow agents to facilitate transactions. Some 400,000 people now work in the private sector in 180 legally approved job areas, Prensa Latina said. That's up from 156,000 in late 2010, the onset of Castro's five-year plan to reform the economy with a dash of free-market activity.
