New complexity is a factor, but I would also point to a reduced standard of living (possibly related). Times are hard. Individuals are worked harder than past decades by their employers, and the goods and services available to them are reduced in quality. So, for example, to get the same quality of food, you have to spend more time discerning its quality or sourcing it from different or more high quality places. Whereas you might have been able to afford a trustworthy handyman to fix certain things in years past, the cost of this is higher and the average individual is less trustworthy, in terms of somebody you want to let into your home.
