Not that I’m aware of? Most PhD grads not staying academia seems to be a long-running phenomenon. The number of permanent academic positions simply does not match up against the number of PhD grads.

Some disciplines are much better at managing the PhD admissions to match the job opportunities. Philosophy for example.

But I don't think that's done with most science PhDs. Is that because of a culture of exploiting cheap labor?

It's not just a culture; there is a lot of government and industry grant money funding (and enabling) the exploitation in the sciences. If applied philosophy is found to be productizable and/or beneficial to National Interest, the same exploitation would grow in Philosophy departments.

Or perhaps because of the vast appetite for the benefits that accrue from scientific research, without wanting to truly fund science and education.
