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.
