Amazon is a major culprit, but not the only one. Don't forget e.g. fast fashion brands. Or appliances brands. Or even restaurant chains.

And of course let's not forget COVID, which was a major factor in destroying small business of any kind.

Big players similar to Galeries Lafayette also fell victim but for different reasons. First (I think) they tend to be well-staffed, so their costs are much higher than e.g. Zara. And second, outsourcing of manufacturing has made a visit to Lafayette kind of pointless: If you are to choose between 50 shades of "made in China", you might as well do it from the comfort of your home.

Also supermarkets. The rot set in before the internet came along.
