I think personally it is because of our atttitude towards retirement planning that majority of the companies today offer either no pension or almost-entirely employee-funded direct contribution based pension system.
My Dad drilled one concept into my head in my early days of career - everybody gets old and every old person wish to retire with pension.
I don't exclusively rely on my employer's pension plan for my retirement planning -- on top of it, I contribute to my state defined (bank managed) retirement funding.
