The majority of the people that frequent this site are above the median income. Being in the tech field gives you a huge leg up economically.

You can either squander that, or you can use it to stay out of debt and build wealth.

Having someone point out that you maybe don't actually make the best financial decisions is uncomfortable and makes people defensive.

Doesn't make the statement any less true. Most people on a tech salary (even outside the unicorn tech hubs) have the means to be debt free and live quite comfortably besides.
