Free travel was introduced in the late 1960s for travel
at off-peak times. The logic was that (particularly for urban bus services) there is a morning and and evening commuter peak while the service runs all day with spare capacity in the middle of the day. Allowing people to travel for free
at off-peak times didn't take away seats from paying passengers, old people invariably have more time on their hands too, so it was a win-win policy.
Fianna Fáil and the PDs abolished this in 2006 (
cheered on by Fine Gael) with very little forethought. There are now over a million adults with the right to free travel
at all times and who can take up space otherwise occupied by a paying passenger. This has real costs in the way that the scheme as originally designed in the 1960s simply did not.
The simplest way around this is to re-introduce the peak-time restrictions on travel in line with the original logic of the scheme.
This is a stereotype that is simply no longer true. Many people who grew up in the 70s actually had reasonable access to third-level or found a job at a time the labour market was booming. My parents and their eight siblings are all in their 60s and gradually getting the free travel pass. All of them have household net wealth (house & pension) approaching seven figures and absolutely none of them have any need for free travel. It is a complete free gift and very difficult to justify.
