Most jobs actuallu. You are confusing familiarity and adaptation with ease. Yes, physically demanding jobs like brick layer are a good example, emotionally demanding jobs like EMT/paramedic too or prison guard, bomb tech, lineman,etc... some jobs due to the difficulty, people who work those jobs have high mortality,suicide, disability and other rates that indicate the body and mind deteriorating as a direct result of the job. Office jobs pay more to the most part but they are not all cushy either. No amount of learning or adaptation can make a hard job easy, only more tolerable. You will sacrifice the same amount in exchange for wages. I did not imply any subtlety, I worked somewhat difficult blue collar jobs and now I have an amazing office job where i can even work from home! I assumed others would also understand the difference. To give you a more first hand example, I troubleshooted networking problems sitting in a nice office and I did the same (layer 1) crawing in attics, outdoors, climbing poles, jumping fences and more in 105+ humid weather and even that was considered easy compared to harder jobs, I was good at both jobs (according to others/management) and I worked more or less the same hours. The difference is night and day. I am more comfortable and much less stressed out when in an offic le job. Even in the office job world, the more I progressed in my career the more rewarding work I was exposed to. Less stress, hardship, more conmfort and pay. No hidden meaning, just an observation.
