A lot of consumer’s buying habits for products with inelastic demand is driven by cost. If companies weren’t driven by ever increasing profits then there might be more of an incentive to offer a wider variety of crops to consumers. Certain crops are already subsidized by the government to make it profitable for farmers. If other crops were subsidized then perhaps farmers would be more encouraged to grow them and if people see these at normal prices they might also be more interested in buying them. Of course, this would rely on multiple parts of farming being overhauled. For example, there’s a lot of cost sinks, one I can think of is the locked down maintenance of farming equipment (once again driven by the need for increasing profits via fiduciary duty). Eliminating these and other overheads would not only lead to more cost efficient farming, but also cheaper crops and increased variety offered to consumers.
The quote you’re using is from the 2010-2011 peace talks. The reason those broke down is as follows:
In regards to Oslo and the 2014 peace talks:
2014:
Oslo: Both Oslo accords were signed, however,
This led to the Camp David Accords where the main issues and points seemed to be the following:
To summarize the 2010-11 peace talks broke down due to Israel not abiding by the terms of the negotiation. The 2014 talks are debated with more blame seeming to be placed on Israel. The Oslo accords were signed but left unresolved and unfollowed by Israel leading to the camp David accords where the main issue seems to be the right of return for the hundreds of thousands of Palestinians who were displaced. However, who actually ended the talks is still debated.
