It's not just starting and stopping projects faster, it's also social norms about changing jobs. We have a much more liquid job market and this provides a lot more opportunities for folks to arb opportunities. This is overall a good thing, but there are side effects.
How much of the liquidy is caused by changing social norms among workers and workers taking advantage of better work opportunities and how much is caused by an unstable job market(with unions losing power) caused by CEOs? Mass layoffs were not always a "thing." They are traumatic to those who get layed off and those who witness layoffs of their friends, family, co-workers, and neighbors without getting layed off them…
Is it any wonder then that my generation has absolutely no sense of loyalty to their employer and show a pathological willingness to jump at almost anything that pays more or has better growth potential?
What benefit is there to an employee that would encourage them to stay with one employer? (To be fair...I've been with my employer for about 10 years, so YMMV.)
