Two totally different economies. People will self-lockdown much more extensively today. Economies were much more local 100 years ago. GDP is also a meaningless metric when measured in currency, and is anyway antithesis of lockdown/war times. Sweden didn't lockdown but is still hit hard economically, and is more isolated today than surrounding countries.
