With so many sectors cutting jobs, what will everyone do instead?

I feel quite stupid asking this but we’ve heard how NHS England is due to cut 10,000 jobs, the University sector is also expected to cut about 10,000 jobs and the civil service is looking to make ‘efficiencies’ which I assume will result in job cuts.

I don’t for a second doubt that all these sectors have huge inefficiencies and that restructure is required.

But what I am wondering is what everyone will do instead? I assume they would need to retrain to different industries but most the apprenticeships I’ve seen are very poorly paid and the government is also looking to restructure/scrap some of the higher level apprenticeships. Another option could be to complete a degree but these are obviously very expensive and you aren’t usually paid whilst doing one. I assume many of the people who will be made redundant will have mortgages and rent to pay and won’t be able to take a huge pay cut to do an apprenticeship or take three years out to do a degree.

Sorry if this seems like a really stupid question, I’m not trying to be ignorant.
