Well yes thats how it works but that doesn't change the fact that a lot money automatically becomes a lot more money. So the gap between rich and poor can only get bigger and bigger.
Are you trolling? There's absolutely nothing automatic about it. You can't make money from interest if nobody's willing and able to make the interest payments. Money lending is a business like any other.First of all education has to be free. No student loans.
Education can't be free. Teachers won't teach if they don't get paid.For the other stuff imagine a monetary system with built in demurrage that kicks in when you hold your money. So lets say I want to build a house and you have 1000 spare dollars. If you keep them under your pillow they will lose value. If you give them to me and I build a house I'll have to give you back 1000 in a year. That saves you from losing money and enables me to build my house. It also boosts the economy because people don't hoard money but invest it.
So, instead of making loans and charging interest, you propose... making loans and charging interest? You realise that's exactly the same thing, right?Yes businesses. But businesses don't have to be owned by one person. Businesses should partly belong to all the people who work there.
So, you expect the employees to pay for the cost of running the business? Maybe you misunderstand the whole purpose of employment in the first place. Businesses pay for employees, not the other around. Who the Hell would pay to work?And to the investors of course.
Why would anyone invest in a business if they're not allowed to get rich off the deal?You do realize that you don't have to eat your money right? You can buy stuff for it like food, water filtration systems, start micro economies, educate people and so on... 
We live in a world of finite resources. Unfortunately, there isn't enough food available to sustain the whole world. Stealing from the rich and giving to the poor doesn't change that fact. In fact, it worsens the situation by discouraging the rich from investing in productive businesses.
