The modern left is never effective. To be fair, it is even questionable if the left was ever effective - besides of course in sending economies down the toilet.
What? Did the left colonize the global south, destroy their economies and slaughter their populations?
The only two countries, the USSR and China, to ever pose a genuine threat to the imperial core have been socialist. The modern capitalist Russia is a disgrace to its Soviet legacy.
As opposed to the right which is extremely adept at sending its own people to the poorhouse in order to slave for the super wealthy. But hey the economy is flying!
Ahaha yes, because Brazil, Chile, Argentina, Bolivia, Cuba, Venezuela and friend that are typically full left are giving their people very good conditions indeed. lol
