I work in a data center with electricians, tower climbers, and systems and network engineers. ALL of us are blue collar. Including me, a systems/network engineer. I suggest you investigate this aspect of tech — there’s more to it than VS Code and JavaScript
Data Center and Operations people absolutely are blue collar in attitude and mindset, but you DC folks get to be isolated.
If you're in a working environment that hires SDEs straight out of Tier 1 Universities, start talking about what it's like to grow up poor and you'll see quickly how everyone's eyes glaze over and you get treated like a pariah.
