They're taking a single week of spending, compared to a time when people were under serious threat of losing their income, and full of fear, and from that one number, they suggest that we've entered a boom cycle.
I'm not an economist, but I don't think the person who wrote this should be able to call themselves one either.
If they're going to go by this number, how about also including the numbers for 2019? Is the economy back to where it was? higher than it was then?
A major boom takes more than just stimulus from the government, otherwise, they'd just constantly be printing money.
I'd like to see reasoning behind the "boom" that is coming, beyond just that people are back spending money. That "should" only get us back to "normal".
