I can't imagine you're getting a huge inflow of people in their 30s or above itching to spend years training for a job where you won't get paid for months at a time at the whims of fighting politicians.
No it doesn’t. They require years of specialized training paid for on the governments dime, and have a mandatory retirement at age 56. Much older than 31 and it simply does not justify the expense of training.
We can always re-examine our priors and assumptions given the current context. It's also worth considering other fields. For example, military helicopter pilots training is longer, more expensive, and frequently only requires a 6-8 year commitment. It doesn't pass a sanity check that a 25 year career should be too much of a concern... if they were treated well.
