I know any economist would tell you that money is based on Gold... and to the best of my knowledge they're right. The PRICE of money for each country is an indicator of how much gold that country owns... this is why if a country prints millions of million dollar bills, it can be cheaper to burn your money then to buy wood with it However, i've noticed that the BASIS of money is non-material... it's a "favour". For example, you are paid by an employer to do a favour for them, so that they don't have to do it themselves. Patrons of a facility pay favours/money to use the facility. i believe however that money could have a better basis, i'm just unsure how it should be based... of course i have my ideas, but i can see holes in them, which means there are likely many i'm not aware of. one concept i had was basing money on energy. Any material can be based on recoverable/potential energy. This means that uranium 235 would be VERY expensive because it's used in nuclear power plants as fule... and food is priced according to it's nurishment value. i have not determined an effective method for pricing non-material items.. because every greedy person wants their profit margin and i don't know a way to make it fair for everyone and still give people the drive to achieve/be successful.
