This is interesting, but it's strange that you would challenge the quality of information due to a missing SSL certificate and then cite Wikipedia, a site renowned for being unreliable and not authoritative.

Wikipedia claims to be up to date, but it relies on World Bank data from 2021. The article (now articles) being contested purport to rely on more recent data, claiming that Russia moved up for the first time since 2014 in 2022 – a year and dataset that is not (yet) captured by Wikipedia.

In good faith, this could be because the 2021 numbers are for the per capita figures, and the 2022 numbers for the PPP figures. But that's rather favourable and would also suggest that per capita and PPP are incomparable. The one cannot be used to dispute analysis based on the other, especially if the person collecting the data treats them as different.

Regardless, if you read the link you posted and arrange the table by GDP (nominal) per capita using data from the IMF, World Bank, or UN, most of the top countries are tax havens! At least 3/10 (IMF), 9/10 (World Bank), and 6/10 (UN). (To be fair, the UN discounts some of those from it's numerical ranking even if they are still in the top ten.)

There's even a warning:

Many of the leading GDP-per-capita (nominal) jurisdictions are tax havens whose economic data is artificially inflated by tax-driven corporate accounting entries.

This data does show something important, albeit unrelated to the original post: the Anglo-European empire, claiming to have no money to improve living standards while it's people freeze, overheat, starve, and suffer from preventable or treatable illnesses, is already at war with it's domestic citizens. Otherwise those tax havens wouldn't exist. The problem for the 'cost of living crisis' for ordinary westerners is nothing to do with Russia (or China) but is due to the fact that it's wealthiest have absconded with all the 'disposable income'.
