The average Developer/Engineer/etc works about 60 hours a week, they work on things that generate millions of dollars. They, for the most part, get paid less than the accountant does. I've literally made a company millions in profit, the entire IT department probably earned less than 10% of the amount of that profit amount. The ROI in IT is extremely high, yet you'll see salespeople whose ROI is much lower making a lot more money. A lot of people will say our salaries being below that of accountants, lawyers, etc is because our barrier of entry is much lower. I believe this not to be true, look at the average job board and you'll see a lot of companies who are literally only looking for seniors. Once you get in, you're fine, but getting in when you don't have the qualifications can be a lot harder. It seems like those industries have spent decades/centuries building prestige into their industries while IT seems to put up with an OK salary with lots of pressure and overtime.

For the majority of skilled workers, IT workers are poorly paid. While we make more than the median salary, the amount of skill, effort, the time it takes to become good at the job is a lot higher than those making the median. You then have the culture of overtime. It's not uncommon to see PRs from people at 10 pm, be told you need to work the weekend, for projects that aren't fully defined and/or have months left to go in development.

Overall, I feel that as an industry, we've massively undersold ourselves and made top-level execs not fully appreciate the value that we as an industry bring. Nevermind the average person, they completely don't value the industry what so ever. The amount of people who default on Web Agency bills who would never default on any other vendor bill is massive. People wanting an ecommerce website for a few hundred pounds.
