It is out of the question that hundrets of thousands are affected in this industry, but frankly, the main difference is that most jobs did not require an up-front investment like the specialized pilot career does, and it takes many years until you eventually reach the break-even point.
A cabin crew who is one year into the business might not have had the chance to save a lot, but a young First Officer looks at 100k+ dept and no chance of employment in the flight deck for ages. Both can compete for poorly payed jobs in the supermarket now but the cabin crew doesnt need to pay back the loan. Soon the type ratings will expire and pilots need to cough up another 1500€ every year for that plus another 100€ for the medical - only if you can demonstrate proficiency without any training as the skills are still fading away quickly without being in a job anyway, otherwise it can be a lot more.
I am not talking about senior captains of major airlines on dinoaur contracts from the good old times who are close to their retirements anyway, but the average newcomer pilot is totally f...d.
