"They bring nothing to the pilot profession apart from a step downwards and because of that, in my opinion, they do not deserve to succeed."
I'm not sure I follow your sentiment... I used to fly for Norwegian and I only left to go home (I was made redundant 2 months after I left in my new airline). I saw nothing but professional and dedicated people at Norwegian, and the pay was absolutely acceptable. Not perfect, but at the upper scale for low cost at the very least. Only long days and too many nightstops out of LGW was really a "minus" as I recall.
If Norwegian folds I suspect we will see an even faster decline in T&C's across the board. The next major low-cost company might not be as union friendly as Norwegian.
Not sure how this will play out, but I hope we will see a better, leaner Norweigan at the other end of Covid-19.
