The argument is that the baby boomers, by being a demographic bulge, have a relatively large electoral influence and so over time government policies have been disproportionately targeted to their changing needs. While 'directly responsible' is a bit of a stretch, at least in the UK voting preferences are currently quite correlated with age (though this hasn't always been the case). Because the current crop of older people are much more likely to vote than younger people, the political parties have made various commitments to protect and increase social security for pensioners. These pensioners are of the same generation that had free education in the 60/70s and then voted for tax cuts in the 80s when they were earning, of course. Yes it is a generalisation, it's far from the only factor that determines policies and the demographic bulge isn't as pronounced in the UK as it is in the US but I still think it's interesting to see how government policies have changed to follow the bulge as it ages. Of course, many baby boomers will tell you that they paid taxes all their lives, thank you very much, and had mortgage rates of 25% etc etc etc.
