Couple of articles I found interesting... Interesting reading here in regards to cash being a store of wealth ???!!! http://theblondgroup.com/2020/05/03/cash-is-not-just-a-dirty-word/ And this report about the UK and their journey towards a cashless society https://www.accesstocash.org.uk/media/1087/final-report-final-web.pdf Interesting excerpt about Sweden and crossing a thin red line "We believe that this is urgent. Not because the system is currently broken, but because it is creaking, with most participants and experts increasingly worried about the viability of the current model, and of the social consequences of uncontrolled market driven behaviour. As we discovered in Sweden, if the whole cash system is allowed to deteriorate too far, there is a point of no return and it can’t be put back. However, if we take action now, we can shape a future which is both economically viable and in which no one gets left behind."
