I will answer part of your question.
It's entirely possible, because the fact that there is a labour shortage, which is mostly caused by the pandemic, does not create more jobs or skill requirements. For example, companies that needed welders don't have more welders because people are out of work. These people are not qualified for this type of position, but they are probably qualified for positions where there is less of a shortage of workers. I can't comment on that.
In summary, the fact that there are more unemployed people does not make these people available and qualified for positions where there is a critical labour shortage.
