Are the .1% are shooting themselves in the foot by hording?

No. When the mob gets riled up, they'll choose their victims, regardless of how well the "undesirables" planned to appease them.

Ideally, the .1% will be heavily prepared and armed and able to put down the rebellion in its cradle, unlike in France and Russia.

The new generation of billionaires (Musk, Bezos, etc.) and even some of the older ones like Bloomberg, mainly the self-made ones, have done more to create a better world for the poor and working class than revolutionary socialists ever have. If push comes to shove, the majority of the non-billionaire class will side with their benefactors rather than those seeking their blood.

The mistake socialists make is thinking that this is still the early 20th centuries, where brutal oligarchs worked ordinary people to death with impunity. It's not. Overthrowing the social order would destroy a lot of the things we "regular joes" benefit from as well.
