O M G, you really cant imagine how rural this place is! We have a higher than average carbon footprint just from all the oxen carts in the street. We have a great internet infrastructure because no one connects to the internet, so its tops like 5 people online per day and you have the whole country’s internet just for you. /s The only reason at this point i dont say to visit Portugal is because we already have enough tourists to the point it disrupts normal day to day life in all the the major cities. Portugal is still on the poorer side of Europe but even so way ahead in terms of services and IT/Tech. Every one has to submit their taxes online so i don’t know how this map came to be. You see old folk quite active with their cellphones doing all sorts of stuff.
Its common but mostly used by people who have multiple income streams or at the time, we have a lot of people working for different countries and one way to make it legal is to be a “one person company” and accountants will take care of it. For the less tech savvy there are programs in the city halls where someone helps people do it. The person still has to do it themselves though, they just sit there with a person telling them what to do.
