this is, again, basic economics 202. Micro is, as i told you in a post before, an incidence count....infection to infection....or if you prefer to it dummy to dummy at a particular measure of time. Macro is anything that scales it. the more you scale it, the bigger the scaling problem. So, for example, let's say you have a group of 10 friends and you all decide that you are going to be very COVID careful: everyone vaxxed, everyone wears an N95, no one goes out if they feel sick, no one goes to indoor dining, everyone is real careful. You know these 10 friends and know they feel the same about COVID as you, and so you feel pretty safe being around them, even with your 5 year old unvaxxed kid, since you know none of you send your 5 year olds to daycare, let alone wander around in indoor public settings unmasked. Pretty safe, right? Scale it up to your local small church group of 100 people..... you know and trust those people and they have a similar outlook to you, but maybe one of them works as a plumber and another has a kid working the lunch shift at mcdonalds. Scale it up to your neighborhood with people who look like you, vote like you and feel the same about COVID as you do. Scale it up to to your city. Transfer it to another city in a red state. Transfer it to Japan (hence your preferred solution we all become Asian).
