I give, what? But there are market forces that cause prices to go up and down as you described. Is your question somehow related to my post?
Not especially, except for the fact you mentioned dissatisfaction with the oil companies.
I believe a lot of the public frustration revolves around the seemingly one-sided aspect of the supply-and-demand formula when it comes to gas prices.
A simple explanation would go a long way, IMO. But it’s always double-talk from TPTB.
