Other folks, it is not so simple or easy. The world is a little bigger than you make it out to be.

When there are several 100 million people to feed in this country, and 6 billion to feed around the globe - then it gets a little more complicated.
But does it really need to be so complicated. I argue that the cities are making it far more complicated than it should be. That's part of the whole buy local issue. This points out just how unsustainable cities are.
Fortunately it is a somewhat free country and you can do it which ever way you want. The trouble is I should not have to bail you out when your investments fail. That is my objection. So the banks / investors made bad choices. They gambled. They lost. Tough. They should not get any bailout. They should take the hit and if it puts them out of business that is their problem. I object that $13,500 of my money, plus interest, has been redistributed to the rich fat cat investment bankers in this $700 Billion dollar bailout. It is that simple.
If your friend quites raising hay, you can perbably find 100 bales someplace else.
Yes, I never single source. I have multiple farmers that I buy hay from. I never give any of them 100% of my business because I want to maintain a relationship with all of them. This way if John doesn't have as much hay as I want this year I call Ray and get extra from him, or Brad, or Jen, or... That is smart and simple. No need for a middleman.
Likewise I never sell to just one buyer. I sell our pork to many different customers. If one customer goes out of business, as has happened, it is not going to hurt me too much. There are other buyers or I'll just adjust my production down a little.
Single sourcing is foolish, on the buy or sell end of things. There is no need of commodity futures or middlemen sticking their fingers in the pie. More importantly, if they are there they are gamblers who should take their losses just like they demand their winnings. Chin up and all that.
For the world at large, & for people living in cities & no hope of personal transactions with individual farmers - speculators are what keeps food on their tables.
Well, that rather proves my point. I've been saying all along that this whole bailout, market crashes and economic recession is a city problem not a rural problem. City people made the problem and they're the ones who are going to suffer the most, as it should be. The middlemen are part of the problem. I object to bailing them out. They gambled. They lost. They should take the hit.
Bailouts is another topic entirely. Can end up between a rock & a hardplace. I agree with you in principle, entirely. When it comes down to collapsing our ecconomy & all - then it becomes a more difficult question.
Perhaps it is time for 'collapse' of those elements that are inefficient like the middlemen, investors and huge banks. If GM can't produce better cars its time to let them fold or change. There are other car manufacturers, in this country and elsewhere, who do produce better cars and do it at a profit. Actions like the bailout protect bad elements so they can continue. Evolution and improvement won't happen if the government keeps blocking out this culling of the weak. Change can be necessary to survival.
Which is the worse evil, to bail out the big cats, or let the small individuals sink along with them?
It is not an either-or situation. There are better alternatives. Let the big cats and any other speculators fail. Let them lose their shirts. They gambled. If they had won they would have wanted to keep as much of those winnings as possible. If they lose they should take the hit.
The problem is the government has said that they are going to concentrate the bailout on helping the few biggest ripoff artists, er, I mean investors and won't bother to help the many of those that are too small to 'bother with'. If you're "too small to save" then tough luck. The government has ruled that the bailout money can be used by these fat cats to buy other businesses, for employee bonuses, to pay stock dividends. That is a travesty. It's just handing over my money to the fat cats. This isn't about saving the economy or country, it's about keeping a small class of wealthy people in money. Let them sink in the morass of their making.
It is unreasonable to demand that working families come up with $13,500 each to pay these fat cats. There are better ways to spend $700 Billion dollars that would help our economy. The bailout as they are doing it is evil.
