Speaking to tabloid Aftonbladet, union general secretary Karl-Petter Thorwaldsson says: "This isn't reasonable. Society would be better if there were more equality."
This is the fourteenth time LO has looked at the income and wealth of Sweden's richest businessmen. However the employers' organisation, the Confederation of Swedish Enterprise, is negative.
Peter Isling, the confederation's press spokesman claims that the median salary for Swedish CEO's is close to SEK 1 million.
"We should remember that Sweden has very small income gaps compared to other countries," he told Aftonbladet.
