Why is risk averse a thing. Blue collar jobs are just jobs unless you are going self employed and buying all the gear etc.

This is a great example of the perspective disconnect.

In trades, the risk is usually not financial. I come home every day smelling of petrochemicals, with minor to moderate injuries, having been on my feet for 8 hours, sometimes up on ladders with greasy boots on, climbing on, into, and out of machines that could maul me without even making an unusual sound, and carrying 100lb sharp steel parts up stairs because it’s more efficient than waiting forces the shop hands to do it.

While the risks certainly have financial components, they’re more “get cancer, brain damage, lose a limb, or maybe even your life” risks. Risk averse is career death.

At least in the factory I worked in prior to becoming a software engineer, there was a significantly higher component of physical risk than in any of the software jobs I've worked in
