What it means is... The first $5000 of consumption will be tax free, the next $10000 at 5%, and the next yet at 15%, etc.

So, the super rich would indeed pay a smaller percentage of their income, only if they spend the same as an ordinary consumer, but they would pay much more tax (e.g. 60% after 1 million) if they spend everything they earn.

This would encourage them not to swap pieces of paper for real goods. It would make them have more money in the bank but less million dollar cars and yachts. The productivity saved from not producing those non-producing consumer goods can be used, e.g., on farming, so that food becomes cheaper for the general populace.

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)
