In other words, regulatory capture at its finest, over the backs of the poorest in the country.
To attain change, enough people have to:
1. Correctly identify the source of their misery, because it ain't [insert scapegoats].
2. Find others who agree with them.
3. Make a plan for effective countering of 1.
4. Use intestinal fortitude and endure temporary setbacks to achieve 3. to overcome 1.
5. Prevent 1. from ever happening again structurally, culturally, and through vigilant participation.
The 0th problem is the political operating system is captured by criminals and power has centralized grotesquely in ways that defeat the fundamental function of separation of powers. All elected officials corrupted by lobbyist bribes need to face accountability and have a code of ethics and integrity, because continuing down this path is the road to ruin.
Are there any common-law jurisdictions in the world where having products on sale in a supermarket is not generally considered invitation to treat but as an offer to sell?
If the price on the shelf were an offer to sell, then you would be contractually obliged to buy everything you picked up. The offer comes instead from when you pass it to the cashier, which is why I'm saying for the third time on this thread, if you don't like that price walk out and leave the goods at the checkout...see if they find it more fun to put all your goods back, or put the correct prices on the shelf! If a group of people did this at every till the store would be effectively closed.
