(Bloomberg Business) -- Mountains of student debt, flatteningwages, and a tough job market have made many people questionwhether ever-pricey college degrees still lead to good jobs.The answer is yes: Job opportunities for college-educated workershave never been greater, according to a new report.

The report, published Monday by Georgetown University'sCenter on Education & the Workforce, found thatfrom 1967 to 2007, the share of high-skill managementand professional jobs rose 14 percent and that thosejobs represent 35 percent of all U.S. jobs. The results belieone widely held belief about the economy: that over the lastfour decades, lucrative jobs have disappeared and beenreplaced by high numbers of low-skill, low- wageservice jobs. In fact, over the same period, opportunities forlow-skill workers declined 10 percent. These low-skill laborroles, such as fast-food server, retail worker,and dishwasher, now make up only 29 percent of jobs.

To arrive at their conclusions, Georgetown's Anthony Carnevaleand Stephen Rose examined data from the U.S. Census Bureaushowing hourly earnings from 1973 to 2007. Thenumbers show that, contrary to the pessimistic views of some,college- educated workers are in significantly more demand todaythan they were a couple decades ago.

"The increasing technological sophistication of our economy hasonly increased the demand for educated workers who can utilize thattechnology," Carnevale and Rose said in the report. "As employershave bid up the price for college-educated workers, the real wagesof high school-educated workers have fallen."

With more employers paying a premium for workers who've earnedat least a bachelor's degree, the college-educated workers havecome to pull in a growing share of dollars earned in theU.S. Although they make up only 34 percent of workers,college-educated workers earned 53 percent of wages in2012. That's a dramatic change from 1967, when workerswho'd only finished high school (or less) made up more than 70percent of workers and accounted for more than 60 percent ofearnings.

"It is time to recognize that the transition from an industrialto a post-industrial economy has resulted in a shift away from aneconomy rooted in high school-level skills to an economy anchoredin postsecondary education and training," Carnevale and Rosesaid.
