From what I can tell, the common perception across the Western world - or at least across the Anglosphere - is that right-wing politicians and political parties are better "economic managers". Even commentary that challenges this notion usually acknowledges that this is the existing presumption.

How old is this notion, and why did it arise? Does it pre-date the Cold War, or did the failure of communism to deliver economic prosperity discredit other left-wing ideologies?

Did the perception arise uniformly across the West, or begin in one country and spread?

Thank you.

Edit: A commentator has suggested that this is not a common perception. Here are some recent examples of Australian commentators talking about the perception as if it is ubiquitous. Of course, they may be wrong - I'm hoping that historians can shed light on that.

In Australia, the notion that the right-wing is/conservatives are better managers of the economy has been described as a "truism", "supported by many media commentators and also by the public", something that "voters instinctively believe" across the Western world and "conventional wisdom".
