The problem Im trying to solve is removing people from the economy who have an unfair advantage. Luck dictates class, lifestyle, and positions of power. It makes sense to me that if we want more efficient and balanced society we need to remove the people with entrenched power who dont deserve it. People who have gambled their way to the top.
If someone before you did something great, sure maybe you should be able to live off that wealth as some sort of gratitude to your elder. If decendents are allowed an advantage, that advantage should have an expiration date and maybe that will motivate them to be better.
Thats my outlook.
This mechanism is one I considered to address this, in a way. A more direct way may blend into socialism or communism but I believe in meritocracy and capitalism to some extent. So maybe this comprise would actually accomplish more of what Id like to see done and its hyper capitalistic.
As far as the question, "what about what we have now" I've spoke about that elsewhere. Essentially we all accept people invest their wealth and are generally not all liquid.
If they spend at around the equivliance of at new minted bill and youre not trying to save them, what does it matter?
If you are trying to save youre not keeping hard cash youre investing it. So then we would see a lot more investment spurring on growth.
