but for how long can they "adjust" to not receiving unemployment and also not working?
You misunderstand what actually happened. Eligible recipients did NOT lose their UE benefits, they only lost the federal kicker amount.
As you know, UE is EARNED, not given, and the state laws dictates its length and qualifications. Politicians cannot pull the rug out from under what their constituents actually funded while they worked regardless of the scorn so many mistakenly view unemployed with. Many of these workers had already adjusted to less income and then got the additional federal benefits which were prematurely taken away by GOP elected politicians - big footing the federal government.
Not everyone benefiting from the added bump were low wage workers. Many are professionals changing careers which often entails acquiring licensing or certifications - continuing education necessary in order to fill jobs requiring such. These people were harmed due to GOP ignorance imo. Sometimes seeking another job is not as simple as filling an application.
But they are dying for workers.....so business is still good.
But business could have been even better. The news has been full of stories where employers have had to increase their pay and benefits, often coming up with creative ways of doing so in the food service industry, passing on some of those costs to their customers by expanding tipping beyond just the wait staff to the entire kitchen.
It still hasn't dawned on most Republicans that child and adult care responsibilities have changed priorities for multiple income households. This is one of the reasons Biden and the Democrats' emphasis on expanding/subsidizing the care industry is a key component to getting more workers into the economy. During the pandemic, people do not have care options and must take care of things themselves, keeping one earner home. And for single parents, far too much of their incomes have to be spent on care responsibilities, something that greater federal funding of human infrastructure will help ameliorate.
