On a more serious note, this must be the first time we can quantitatively measure the impact of cookie consent legislation across the web, so maybe there's something to be explored there.
I work as a senior engineer in Europe and make barely $4k net per month... and that's considered a "good" salary!
And you have (almost) free and universal healthcare in Europa, good food available everywhere, drinking water that doesn't poison you, walkable cities, good public transport, somewhat decent police and a functioning legal system. The list goes on. Does this not impact your quality of life? Do you not care about these things?
How can you have a higher quality of life as a society with higher murders, much lower life-expectancy, so many people in jail, in debt, etc.
Europe on the other hand can't even manage to defend itself and relies on the US for their sheer existence.
Cookie notices just gave them another weapon in the end.
By the time someone buys their own pack they are probably hooked.
I suspect the obscene taxes blocking out young folks is one of the most effective strategies
