I'm not sure how shutting down Porsche factories is going to make food cheaper? In western countries only a few percentage of people are in the business of producing food. By moving workers from building yachts into food production will not make food production cheaper.

This plan would see the rich hording money, rather than spending it on luxuries. The kind of luxuries that are produced by western economies. When the rich spend their money on frivolous luxuries, it helps redistribute their wealth to the workers producing those luxuries.

To take an example to the extreme, it would be wasteful if Warren Buffet hired 10,000 painters to paint a portrait of himself everyday. The GDP would go up, but it wastes effort, effort that can be allocated more efficiently. (Using his own example here)
