Means-testing just makes it pointless to save, is expensive, and can also be embarrassing for those who qualify. As it is, if everyone has a pass nobody can tell who is on benefits and who isn't.
People were furious when WFA was means-tested, and nobody knows who is on PC unless they choose to disclose it. Many people complained about those just above the PC limit who are there because they paid into a work pension, and I agree that it is unfair to penalise people for doing so (or rewarding them for not, if you prefer).
Bus passes would be more of the same if they were means-tested, and could result in someone with a small works pension losing their WFA and not being able to visit friends and family, when their neighbour who is on benefits gets both a bus pass and the heating allowance. That would be very unfair - means-testing almost always is.
The government is currently trying to incentivise work, so penalising people for doing so by taking their bus passes would fly in the face of that philosophy.
It only makes it "pointless to save" if you are expecting to come quite close to the means-tested amounts.
However, your comment brings forward the critical reminder that "it's not the people who abuse the systems it's the systems that abuse the people".
Many challenges - such as inequality, injustice, and discrimination - arise from the design and functioning of such systems, in politics, economics, education, or healthcare. These systems can perpetuate harm to individuals and communities, often in ways that are invisible or normalised.
It also highlights that, while individual actions can certainly cause harm, individuals often operate within constraints set by larger forces. If a system is inherently unfair or flawed, it can produce negative outcomes, regardless of the intentions of individuals within that system.
I use this phrase when people - not unreasonably as they are lead to think in this way - find a particular group to blame. I hope governments will pay more attention to those at the edge of a system. But I don't, for one moment believe the government is biased against the under 65s. That headline is part of a "foolish consistency" which Ralph Waldo Emerson defined as “the hobgoblin of little minds, adored by little statesmen and philosophers and divines." There are many such people in both journalism and politics and sadly, on forums.
