Answer:
"No politician will sacrifice short-term economic welfare" is a concept that implies that politicians, in their desire to have a positive political image (with the aim of winning elections and staying in power), do not take measures that, despite If necessary, they may affect the economy in one way or another in the short term, as this notoriously affects public opinion and leads voters to seek other alternatives to the rulers who have taken such measures. Thus, measures such as economic regulation with the aim of protecting the environment are avoided, since they affect the economy in the short term and tend to subtract votes from politicians.
