I am glad I could present some points to help you think more about the career!
I don't think the company will decide whether it is a entry level job or advanced level. They will offer that price and it's up to the artist to take it or not. Usually a seasoned artist with 5 or 10 years of experience will be able to say no to such offers (or maybe not even waste time looking for them).
It ends up on the hands of artists starting their careers. We know some starting artists may be quite good in terms of artistic skills and they may think this is a great opportunity. Or maybe, some of these starting artists are just desperately needing money and they accept the offer.
As for the quality of the materials for analog art, I agree that better quality materials have an effect on the quality of the creation, but I mean that a good artist can use a 2 dollars sketchbook and a 10 dollars watercolour set and make a piece that is much better compared to a bad artist that invested on high quality materials. So, I believe the beginner artist should invest on becoming a good artist. The seasoned good professional artist is making money to be able to afford good quality material in case the work he is being paid for requires higher quality material (or maybe he just want to have fun with new materials :P )
P.s.: just a detail... I used the term "analog art" instead of "traditional art" because I think the term traditional is very misused. I think even in digital art, there are techniques and processes that are not used anymore and are therefore "traditional". For example, nowadays in 3D computer graphics its very common to create characters by doing digital sculpting (high polygonal sculpting) while in the past it was done by basic geometry modeling (low polygonal modeling). So, the low-poly modeling can be considered a traditional way to do 3D digital art. Or even in non digital art, someone can be using a new technique that was never used before - I think using high tech machines to cut metal to make a sculpture is a very "non-traditional" way to do sculpture, which is not digital at all.
