Sorry, I didn't intend to apply a causative relationship, and should have worded it better. What I mean is that the policies of modern Peronist ideology clearly aren't effective, but (outside of the failure of the centre-right Macri administration) I haven't seen any serious attempts at something new. It's always "More wealth distribution!", "More grandiose infrastructure projects!", "More involvement of the national government in the economy!", and things along those lines.

Edit: To clarify what I mean about Macri- no one has been able to marshal a national consensus to try something new. I still can't believe Macri got as far as he did. Most of my friends call Macri a far-right extremist, but I would say that the policies of the Macri administration were centre-right by the standards of most western democracies, and would be considered leftist by US standards.
