Only if this "more rewarding work" is available and at above subsistence level (nothing rewarding about doing what you like but barely being able to make ends meet and/or not being appreciated for it, which in the end destroys your enjoyment of your line of work too).

And only as long as people aren't hammered 24/7 with ads and consumption imperatives -- a lot of people believe those can be easily resisted and that they never buy anything because of these etc, but statistically most of them are overestimating themselves, they are as susceptible as anyone to consumerism persuasion which includes ads, fashion, peer pressure, status signals, being more attractive to potential partners and tons of other things besides.

Yes in theory but most work is organized around salary and freelance work is usually more work instead of a salary, so worse. The salary structure forces the type of logic I am writing about above. Every company wants to make as much profit and remain competitive. Therefore they don't really have the opportunity to provide easier or better work. Or even signal that with the amount of money they pay for via a salary. The economy does not do this at all. Read all job descriptions, they are all filled with terms like tight deadlines, etc.
