Tenure-track faculty positions are hard to fill in this tech market no doubt. However, with multi-billion endowment at top schools, couldn't they pay competitively at least for part-time lecturers with PhD and some teaching experience, who might be working in the industry, to fill in requisite teaching needs?

I guess if the above is adopted, there could be issues with part-time adjuncts getting higher hourly rate, by some measure, than tenure-track faculty. Thus, a market-based bonus which could fluctuate with market conditions of each field for tenured or tenure-track faculty members should be considered.

Added: By hard-to-fill, I meant hard-to-fill to the qualification threshold of research universities implicitly referred to in the article.
