They are not the only business or industry who keeps their heads in a glass bubble.:annoyed: A knowledgeable manager of any business understands that the customer does have limits - just because you put a price tag on something for the amount of money YOU think it is worth, does not make it so.
Some segments of business have a harder time understand that - sales is one. Some sales organizations price items too low for manufacturing, so as to easily make their sales quotas. Others price themselves out of the market, but use false promises to imply a better product with smoke and mirrors, etc.
Timeshare systems seem to believe their own marketing hype. What worked 10 years ago, does not now. The internet, the employment status, morals of owners (i.e.walk-aways), vacationing modes - have been external changes to their business environment. US car manufacturers have been a prime example in the past 15-20 years of failure to adapt.
