I think the question in the areas you’ve mentioned should be “Are Engineers more bullish about housing?”.
I’ve been around engineering for years, and engineers are smart people, but many have no clue about economics and money.
I currently implement ERP systems, and specialize in finance including payroll. I’ve seen the largest variances in pay amongst engineers. I’ve routinely seen companies where guys doing the same function, 10 years with the company, same job titles, and a group of them will make 70K and another will be at 95K.
