Meals in countries that take food seriously last longer and are meant to be enjoyed with family and friends. Its just our shitty culture that causes this problem.
If food is viewed and enjoyed as an experience rather than a necessity as a culture, I think it leads to huge shifts in so many aspects of daily living.
The US also has literal holidays centered around sharing a meal with friends or family. Thanksgiving turkey, 4th of July barbecue...
I'd wager the reason people eat in 10 minutes instead of an hour is the same as it is everywhere else: after an 8 hour workday, you feel like all you've got between work and sleep is a few hours and you don't want to waste it on something boring like eating.
I'm not American, I'm Estonian lmao, but I bet you're one of those Americans who wants to seem cultured so you talk about how much better things are in other countries? Am I wrong?
Edit: Nvm, Canadian - but up till like 2 months ago you guys were America Lite tbh
