GA pilots also have to pay mortgages; they don't get housing provided even if it is sub-standard; they don't have Officers/sergeants/ airmans messes to provide their meals either.
the vast majority of Mil married Mil pilots i know own their own homes and pay mortgages. The reason housing is provided is because they are required to serve anywhere in the world at short notice.
The vast majority of Mil pilots are GA pilots aswell, when they're not away in "sunnier" climes".
