Wallenberg, who is also chairman of the Wallenberg Circle's investment company Investor, tells the Financial Times that decades of business-friendly reforms from both the left and right are now in jeopardy due to various opposition proposals.
Among other things, he believes that Sweden risks losing its world-leading position in start-ups and that even established companies could be affected if the opposition were to win the election.
"The opposition has pointed to more government involvement, higher taxes in a number of different areas and also a discussion about working fewer hours. I am deeply concerned about these things," he says in the interview.
It seems counterintuitive that you become more competitive by working less and by making it harder for companies to develop, he adds.
Social Democratic Party leader Magdalena Andersson says she understands that Jacob Wallenberg, as chairman of the Confederation of Swedish Enterprise, wants to put forward his views in the election campaign. But he is, in short, wrong and has nothing to worry about in the event of a change of government, she claims.
"I can only state that Social Democratic-led governments have performed with growth above our potential, right-wing governments below our potential. We usually have good employment development and order in the finances," says Andersson, referring to Sweden's potential.
