If this is just from foreign sellers operating on amazon.it, then 1.4B of evaded taxes sounds like a lot to me, because the total revenue should be well under 50B/y, so this would be a significant fraction of total sales tax (and I'd expect most sellers to not be foreign and thus unaffected).
Would be quite nice to see rich people held accountable for once, curious how this will go.
A regular citizen doesn't pay tax: lets jail or deport you, bar the entry for a decade, take away your home, car and anything you own in general and make you unable to find job for the rest of your life. Also your tax is double that of the billionaire, glhf ;) .
