Observed mask usage?
Sweden - 1 in 25 people
United States - 3 in 4 people
Daily infection rate? Rates were comparable early on. During the summer months, Sweden's rate fell to next to nothing. During this winter's second wave, Sweden's daily infection rate per capita remains about 40 percent lower than ours and is projected to remain lower than ours, even with projected mask usage remaining the same.
And this data doesn't even account for reduced social distancing in Sweden due to more businesses being open (in particular, bars and restaurants).

Bottom line - lockdowns don't work. Masks don't work. We're destroying certain segments of our economy and giving away our freedoms for NOTHING IN RETURN.
Looking at that data, it looks like summer weather had a FAR LARGER impact on slowing the spread (like, orders of magnitude) than did anything we tried to do artificially to slow it down.
