Nothing will ever change - as long as businesses are allowed to run on their present lines!!! The US and the UK run along similar lines which virtually guarantees that any large company will eventually bankrupt itself!
A CEO is retained by a company for an average of between 3 and 5 years only - yet a large company such as an airline needs a realistic 20 year business plan. In the 3 to 5 year life of a CEO, it matters not a jot how badly he/she performs, they are paid sufficiently well to retire for the rest of their natural lives should everything go pear shaped.
Should business leaders ever be held accountable financially for their company's downfall, that will cahane business for the better!!!
