Retired people aren't working any more and require some level of resources to take care of them. The higher the higher the ratio of retirees to everyone else grows, the higher the percentage of society's resources will be spent on them. This can take the form of higher taxes to pay for more and more socialized healthcare, but even in a libertarian utopia your dollars are competing against theirs as a higher percentage of the workforce are employed to care for them. If you're a young person who's still working, it's not an attractive outlook.
