This is why the minimum barrier to entry into this program is having an income of ISK 1,000,000 per month, which means that you need a salary of over €80 000.
Additionally, they also don't want foreigners to actually settle in their country, which is why there is a 180-day ceiling. The purpose of this program is to have rich foreigners come for a spell, spend lots of money, then go away. They're being very transparent about this.
