I would say that, it makes no difference who is in charge. The demand to provide more for less money and the power of the stock market lead in one direction only.
Even LCCs have this problem. In the USA, Southwest came to focus on the money so much that they were part and parcel of Boeing choosing to reduce training on the Max conversion. That has not worked out well.
The current pressures on companies compels them to provide poor quality. Whilst the public moan about the quality, they still do not want to pay for better.
