Nope, just confirmed again. The only way around it is to go with a business account, which even the cheapest option costs 2x the price of just you and your wife both having Plus accounts of your own.
It's a solution not without compromise in terms of management and accounting but does achieve an outcome that would fit the apparent need.

[1] It might if dropbox was a more lean operation, but it isn't.
I may be misunderstanding your question, but it seems to me that this is literally the whole point of the service. Dropbox is a folder that syncs. You change something on one device (one write), it updates everywhere (multiple reads).
They do have some tricks to lower their bandwidth usage. AFAIR, if multiple devices are in the same LAN, only one gets synced with the cloud, and the rest sync to that one. Also, they have (recently introduced) a sync option, in which fake files are visible in your file system, but no actual contents get put on the drive until you try to open them.
I thought that was a first in the earliest of versions and was one of my favorite. At some point they removed it and made you choose which folders to sync. At which point I abandoned using it. So maybe they are reintroducing it or I am misremembering something.
(I think a good Linux analogy would be FUSE, things like sshfs.)
The postal system solved this problem ages ago, you charge the sender postage. Done.
"Differential sync brings the ability to sync only the parts of large files that have changed, not the entire file. This makes the file synchronization process faster for these files. Currently OneDrive supports differential sync for Office 2016 files. Later this year, Microsoft will bring the ability to leverage differential sync to all file types stored in OneDrive and SharePoint."

Edit: It went live on November 4th 2019:
"To complement these large uploads, we announced availability of differential sync for PC and Mac, bringing the ability to sync only the parts of large files that have changed, not the entire file."

OneDrive was inferior, no doubt, but good enough. And will only become better.
More importantly, I cannot imagine anyone building better integration with Office (live editing) than the actual Office company.
After working with their stuff I totally can :)
Joke aside, MS is doing a great job commoditizing the space around Office 365 with Teams and OneDrive. I think DropBox and Slack are feeling a lot of pressure right now.
I'll hold my breath. Dropbox basically had sync across all major OS's ready to work very early in its life (10 years ago?). The fact that OneDrive and Box's desktop sync performs so poorly leads me to believe this is not where their engineering effort is and nor will it anytime soon (it's probably more on the back-end admin for enterprise clients).
My company currently does this currently, as we wait for a more seamless system to be set up. So it does a write every minute of the day to a Dropbox sync folder. Which only syncs up once every few minutes. So essentially I do miss a few minutes in a day, but since it's just a human consuming the data, I don't mind.
It's also the only cloud storage provider that allows you to have files-on-demand feature on free tier account on Mac OS. Others (Dropbox and Google Drive) only enable it at on Terabyte plans.
The protocol is actually available for any cloud storage vendor to work with: https://wopi.readthedocs.io/en/latest/

(1) exception: you can have one personal and one business account
First run (installation): `HOME=/path/to/client-specific/home/folder dropbox start -i`
Subsequent runs: `HOME=/path/to/client-specific/home/folder /path/to/client-specific/home/folder/.dropbox-dist/dropboxd start -i`
Edit: Each "home directory" here can be any folder; you're essentially presenting a fake home directory to each Dropbox process. The dropbox processes can run under the same user.

Edit: I use Google Drive because of Google docs. sigh
I've moved to the US after that, but I didn't bother changing the location on the MS account.
I want to be able to pull/push/ls directories at a minimum.
Dropbox surely had its share of problems but in my experience with the 400 GB archive that I have is that Dropbox was the only one with a decent client that actually works.
In general you get what you pay for and €10 per month doesn't break the bank.
I hope they'll survive because I don't think I can find a good replacement.
