Are the baby-boomers a lucky generation or a selfish one?

Altogether Spanish people are worth about € 7 billion. This can be divided roughly into € 1.7 billion in personal financial assets (shares, savings,etc) and € 5,5 million in housing.
It is logical that older people should have accumulated more wealth than younger ones. But the proportions according to an insight achieved by Banco de España seem to be shifting sharply in favor of the older cohorts, especially those aged 55 to 64. Comparing the financial and housing wealth of different age groups in 2002 and 2005 the Banco de España found that those aged 55 to 64 had seen their wealth almost double. Young people have little chance of building up similar wealth. They are struggling to get on the housing ladder, though close to a third of people between 55 and 64 years old own a second home.
Baby-boomers can chuck the job at 60 or 65 and head off into the perma-tanned sunset while their children must drag towards a receding retirement age e.g. 67, as in recent times proposed by Spanish Government, as a paramount proportion of state spending is dedicated to the needs of a mammoth generation of the elderly.
Spanish baby-boomers tended to believe their houses were all the piggy bank they needed. They neglected to make other comparable savings.
Prolonged economic growth tends to make people assume that future generations too will grow richer, and hence to make less provision for them.
