I didn't even know that you could bring treads that are 10 years old. This is the oldest I have seen in a long.I think you really do have to distinguish between teachers in the States and Canada. There's a really wide salary difference. Teachers here in Canada (and I have teachers in the family) are very well compensated, especially when it comes to summer breaks and benefits.
Likewise, the teachers I know are anything but frugal, though I guess it depends on standards. The teachers in my frugal family are the least frugal of the family. But they're also the most frugal of the teachers outside of the family.
I imagine teachers in the States might be less frugal than 'poor'.
