My nitpick is that comparing salaries without the relevant pay raises is a very bad idea, because different jobs have different rates of pay increases, different pay ceilings, and different levels of stability (if you have to jump workplaces you may lose income during the gap).
Engineering looks something like this:
$60k with 8% raises until about your 8th year or so, then you hit a pay wall and have to either go into management or get marginal pay increases after that, also, the raises aren't quite incremental year to year. 45-50/hrs. Overtime rarely happens. Telework impossible. Decent job security
Examining looks like this:
$70k with 15% raises until your 10th year, then you hit a paywall and get NO raises at all aside from inflation and increasing your pension amount. 40 hrs, 100% telework very possible after 2 years. Overtime is not rare, though it is shut off for long periods at a time. Good job security.
Prosecution looks like this:
Pay ~$250k upfront in tuition and lost income to go this path. Make $60-140k 1st year, 2nd year will be 125-145k, and after that, 2-4% raises until your 6-8th year. Then you either become partner or go in-house, where your pay will go up about 10-15% a year as long as you can stick with the same place (if at a firm you'll have to pull in clients, if in-house, you will have to become something like a VP) and you cap out around $300-400k 20-25 years in. 55-65 hrs, telework is mostly only on weekends possible or doing overflow work. Overtime translates into high billables, usually meaning spending well over 60+ hrs, way past normal overtime. Bad job security, but fairly easy to find a new position, but not necessarily nearby.
Pretty extremely different payscales, work hours, and working environments. If you plan on a long career. and want to work a lot of hours and make a lot of money, patent prosecution looks great, but otherwise, it has a lot of downsides that are not compensated for until late in the career, after paying a lot of dues. It is also a gigantic waste of money if you attempt to do it, fail, and then have to go back to an engineering/lab job.
