Care to elaborate?
Not necessarily. It could be things they don't need but just have an excess of.
Look you didn't get my point. What if the farmer was more productive than other farmers? what if he discovered techniques that enabled him to produce twice as much as the average farmer? thrice? or even more?
He could share those techniques with others.
Can't he exchange that excess produce for other forms of material wealth whether it is jeans, gold, cookies, or sofas? won't he be "richer"? wouldn't that mean he would have more power and influence than others? and with time, isn't there a possibility of an affluent class rising?
Socialism, like capitalism, is an entire system of production. Except it's based on collective ownership and democratic control of the means of living and the natural resources. But also like capitalism (and any other mode of production), it will produce a surplus. This surplus, too, is collectively owned either becoming social or personal property.
The system of production will accumulate surplus which is shared collectively. If there's a bit (or a lot) more left over all good. Bear in mind that no-one has truly derived power from having too many apples; they had to disposes others.
Unless there is a state imposing wealth aggregation limits, I can't see what's preventing that from happening.
Let's assume it's an uninhabited stretch of fertile ocean shore in Ecuador. Can anyone just go there and build a house? if so, how can he protect the house from others who might wanna seize it?
If there's a state whose role that is it will constitute a ruling class who actually own the wealth. In other words state-ownership - capitalism, again (or worse).
That's why such an institution is incompatible with socialism.
Socialism like anarchism involves the absence of money, classes, and state-governments.
Enough of what? wheat and barley?
Food, shelter, water, medicine, transportation, communications etc..
But seriously, people will always want the best be it the latest iPhone, prime kobe beef, luxury automobiles, or vintage wine. And I don't think we have enough of that.
Just because a relative minority of the world have in recent times been told constantly through propaganda they want those things all the time, and often seek them, doesn't mean that's what they need, that people always have, and always will want them. Anyway, I think there are already enough cars, computers and telephones around for everyone to have access to them. As long as there's farming of any kind there will be alcohol. Vintage wine is over-rated, anyway.
I mean, really! I don't think there are many people around the world who would prefer a new television to free food, water, shelter, medicine etc.. all at the point of need.
BTW, are you for the abolition of money?
Of course. Money and exchange values of any kind are incompatible with real socialism. No private ownership = no money.
