CL300, I fully agree with your recommendations (Part 135 equivalent in Europe), however I see another reason to the deterioration of the quality of life of many : flying is expensive but a lot of people among our industry, helped by the ego of some clients and driven by as futile as short-term as mercantile motivations, tend to make believe the opposite.
The result can be under-crewed aircraft flying illegal charters with an aircraft which should have been grounded for maintenance. Maybe "good" for a young FO willing to become a Captain early. Not acceptable if you have 4000H of bizjet command close to retirement, a house paid and kids flying by themselves.
On the other hand (I hope I don't disclose a big secret here) those "make-it happen" operators help the entire industry: imagine if 35% of the bizjet/turboprop fleet were being grounded tomorrow...
