Doesn’t Amazon also function as a platform for small businesses to sell their products? For a fee obviously, but at least offering the infrastructure that might otherwise be difficult to obtain individually?

Anyway, besides that, I would argue we are speaking of a variation to an old theme: change is inevitable. Panta Rhei. Science. Industrial Revolution. The Mayor of Casterbridge by Thomas Hardy. Global labour arbitrage. You’ve Got Mail with Meg Ryan and Tom Hanks. Monthly mobile phone bills decreasing from hundreds of euros to only a few dozen. Air flight available for the masses. Etc.etc.etc. the list goes on ad infinitum.

Will small businesses survive? Yes, some, but not many.
