It's a triple whammy of
>less disposable income
>lower trust society
>fewer cool convertibles on offer
No one wants to spend what little they might have on a toy, let alone one with a ragtop prone to being slashed open by thieves. No one wants to ride around all vulnerable with their top down while living in clown world. Plus most convertibles now look gay and compromised. I mean look at the cars in the OP. They're all for 60 year old white women except the Miata and the Boxster. Solution: unjew the economy, deport hostile foreigners, make cool looking verts again
