There are lots of reasons named for why churches are changing, such a more secular culture, wider social options and the rise of the Internet. But reasons related to resources make the most sense to me. Is this thing -- an organized religious life -- worth money to me? And time… is it worth my time? Increasingly, the answer is no.
Time to attend services -- and commute to them. That's a problem for Unitarian Universalists outside Massachusetts, who are usually organized at the municipal or multi-country level. And it means that the volunteer time we ask of people should be valued very highly. Perhaps so highly that some labor-intensive activities need to vanish.
They can be retired, left to starve from disinterest or (worse) be resented for the precious labor they demand. Volunteers deserve to be treated as scarce and valuable resource; if not, others will do a better job tending to them and the churches will really be strapped.
