It's a short term circumstance they are exploiting to make themselves look good.
We've had the lockdown thing for a year, masks, government handouts for people to stay home, extended benefits for staying home, small businesses punished where they had to cut back or close.
Now the vaccine is rolling out big time, restrictions being lifted, benefits running out, no more stimulus in our future. Of course the economy is going to look better, not because they did anything in particular. It's just because covid stuff is being lightened up on a lot.
Even if overall the economy is 40% worse than it was this time 2 or 3 years ago it's still going to be a vast improvement over what it was last year.
