The explotation thing was a bit tongue in cheek, please don´t latch on to it. You are disregarding the main point I wanted to make, you can´t implement a UBI system if your economy is going to collapse. And it will, for example the Spanish economy would, because low paid jobs in industry and the service sectors are sustaining the economy. If you implenent UBI, where will you find steelworkers, assembly line workers, fruit pickers, bar staff? Will people work those jobs as a hobby? Nope. You´ll have to increase the salaries. Then the industries will be non-profitable and will close. Tourist resorts will be more expensive and tourists will stop coming, they´ll do to Tunisia, Turkey or wherever they offer cheap stuff.
