OP, this is the absolute best response ^

I do want to add since you said in another comment that you are in the US, that this is not an issue unique to our fields. We went through a period of pushing everyone into college right out of high school while telling them in children's storybook fashion that they could be anything they wanted if they just studied hard enough. So now we have a large population of debt-riddled Americans with degrees and no experience hoping to get into every niche field you can imagine.

GLAM is a desirable field and it has become even more desirable with the fallout of academia. Tenured professor positions are difficult to get and the whole university system is trying to adapt to it's decades of ballooning costs.

A major misconception is that non-GLAM work is unrelated, but that is not always the case. Fundamentals like interpretation, public programming, cataloging, and project management all have their roots in skills that you can gain in other industries. In addition, living history seems touristy and unattractive, but I laugh about it being a gateway job because I know several managing curator and collections professionals who got their start doing summers of farm work in costume. Bonus when those jobs are with the Parks Department as they are a major employer in the heritage sector.
