I'm sure you must be quoting some knowledgeable source. Which numbers are "down 80%?"
Tourist numbers are down approx 80%,which makes sense as capacity in SXM is down 60%.
Revenues in shops (clothing,wine shops,jewelry that i know about) are down 80% or more..:Walking in Gustavia at 18.00 last week,i guess luxury shops are not doing much better.The lack of yachts must massively impact them.
Some restaurants are also not doing that great (specially the ones open for late dinner,as nightlife evaporated).
It would be interesting to know how shipping problems impact businesses.Some renovations can't proceed because of delays.
As i said earlier ,this was expected.
The real problem is going forward,according to my conversations.A very slow mid season seems in the cards.
