No, I'm a professional, and I expect to be compensated appropriately for my time and effort, just like the lawyers and accountants and other professionals I pay in turn.
I don't understand your unwillingness to accept this way of working. You seem to assume that it will result in a lower total income. I have encountered no evidence that this is how real life works. Maybe it's how the game is played in your particular field and/or your particular location, but it's certainly not universal.
Also, like some others posting here, I do value the ability to work on multiple projects simultaneously. I don't want to commit an entire week of work to a single client on a single project, if that is neither interesting for me nor providing good value to the client.
Also also, I like not being expected to stick around free of charge for another two hours after an 8-hour meeting 100 miles from home because my client wants a quick chat. Indeed, if my clients need me to attend a meeting 100 miles from home, I'll be happy to do so, but they're paying my full consulting rate for the travel time as well. When you're working on a day rate, particularly a relatively high one, it's funny how often your days start to become more like two of my days.
