Trickle-down economics is a dead simple theory, why do you need someone to explain it to you to have a conversation? Just so you can continue on presuming the stupidity of those who think it's an inane demand?
What isn't fair in a democracy is not that others have more, it's that a dollar is worth more than a vote. Politicians are elected to represent the people, but the current system represents special interests far and away more than the people as a whole. You can see this in virtually every kind of legislation. Corporatocracy, plutocracy, crony capitalism, whatever you want to call it - it isn't democracy.
Giving the wealthiest of wealthy more money does not typically produce much economic growth - there are plenty of papers on this if you'd like to do some research for yourself. Instead, they just end up controlling a larger share of the economy. You're not out to own more "stuff" at the top, you're out to gain more power which our system easily allows you to do.
This, I think, will effectively eventually lead to corporations controlling the world. And they are trying - one of the big reasons I liked Trump was because he was against the TPP. My fucking god what a rights-stripping corporation takeover attempt that piece of shit was. And written in secret of course, because the public can't be a party to the conversation of taking their rights away.
Fairness in a democracy is one person one vote, not one dollar one vote. Remove money from politics - lol. Tax the wealthy a lot - definitely not ideal because a smaller government is a better government, but it is somewhat of a stopgap. Alternatively, find a way to distribute the growth of the economy to all citizens more or less equally. Communism! you might say. Except virtually all growth in the economy goes to Wall Street or London like leeches when they produce absolutely nothing of value except digital zeroes. The productivity of the people is sapped away by these leeches and it shows in the widening wealth gap.
Care to discuss civilly?
