Slogans are mostly used by clueless people aimed to impress clueless politicians and usually end up in clueless law.
Examples:
SA is capable of producing enough grain for its own use, export, donations to other and use the balance for producing biofuel. Because of slogans the decision was now made not to allow it. This is a major blow for farmers because the prices may drop to below production costs. and no subsidy for not producing is available. Oil imports will have to increase. I don't think all the pros and cons were considered.
SA has a healthy elephant population where culling is required for balancing. Due to slogans the sale of ivory is forbidden resulting in a big stockpile of tusks. The ivory should rather be sold and the funds should be used to improve the environment.
A relief was approved - but I don't think responsible protectors should beg for permission.
What do CR4 think.
Maybe we should also resort to slogans. What would be the result of "FIX THE STUTURE OR THE BRIDGE WILL FAIL" be?
