-Even running the model with conservative values (say 1.5 skill variance) reveals a strong and fast trend of the rich getting richer and the poor getting poorer. Also, while running for a while, we see the 'middle classes' getting completely wiped out and almost all wealth gravitating to the richest 10%.+Initially running the model with agents set at the same minimum skill level reveals no significant increase or decrease in wealth.

 Also it should be noted that there is no debt and only those who can 'afford' to pay are selected as customers at each cycle, however these 'poor' agents can still sell their skills as per normal. Also, it should be further noted that no amount of extra wealth or energy enhances any agent's ability to sell their skills. Also it should be noted that there is no debt and only those who can 'afford' to pay are selected as customers at each cycle, however these 'poor' agents can still sell their skills as per normal.

 ===== Safety net ===== ===== Safety net =====
  
-Since the model effectively 'kills' off poor agents without mercy, I decided to add a 'safety net' feature which would roughly mimic the effect of social safety nets like state welfare, charity or microloans. Once an agent is in danger of falling below this 'poverty' threshold, they are awarded an extra wealth credit freely. This credit is then taxed across all other agents equally.+Since the model effectively 'kills' off poorer agents, I decided to add a 'safety net' feature which would roughly mimic the effect of social safety nets like state welfare, charity or microloans.

 +While this is an effective way to rescue agents from the poverty line, it makes little difference to the trend of the rich getting richer, except slowing it slightly. (NOTE: A higher safety net figure could be used to simulate a universal basic income)

 +===== The transfer of energy ===== 
 + 
 +In this model, wealth and energy are tracked independently. 'Energy' generally refers to work / effort and quality of life. ie. Agents 'spend' energy selling their product, and 'consume' energy that they purchase from other agents as quality of life.The greater the energy they have, the higher is their quality of life. 
 + 
 +In this simulation, all agents spend exactly 1 unit of energy 'selling' their product regardless of price. This would appear to be a fair reflection of the similar amount of effort it requires to put in a day's work regardless of salary. 
 + 
 +{{:pic7.png?550x275}} 
 + 
 +Tracking energy instead of wealth reveals a completely different distribution where all agents are in the ascendancy. 
 + 
 +{{:pic8.png?550x275}} 
 + 
 +Even though some agents are 'selling' more energy than others, the net effect is that the net increase in energy across the population is roughly evenly distributed. 
 + 
 +===== Conclusions ===== 
 + 
 +Even though quality of life generally increases for all agents, there is a significant cost in terms of inequality and the suction of wealth from society by the wealthy. And it's worth emphasising that there are no greed or privilege elements in this model; the gravitation of wealth to the wealthy is simply a mathematical function of their costs becoming proportionally less and less. 
 + 
 +When both the transfers of wealth and energy are taken equally into consideration the net benefit to society is only marginal, whereas a society hypothetically based on the transfer of energy //only// (open access) would be significantly better off.
