enterprise connections pay a premium, and smallish employers often don't want to spend money on monthly expenditures, so mostly ~50-200mbit shared between all people at the office
You can get 1g down, 50mbit up for less than a tenth of that with cable for example. We used that line heavily and I loved it, but I'm still unsure if I should rather have spent the money differently.
We've moved now to a WeWork Style Location ( Studio from Tishman Speyer ) and are down to 100/100, have put our vpn equipment in a datacenter for 70€/m and nobody complains.
The most efficient way is probably to get consumer cable through the CEO(for "private" access to YouTube etc) combined with a smallish business vdsl connection for everything company related.
They do know that consumer internet is asymmetrical and not practicable for real work.
FYI ELM (ethernet last mile) at 70Mbs in the UK costs about £70 pm
if your business relies on connectity, best to avoid it.
