One success story is in the Reaganomics era in the US. Tax cuts were implemented based on the Laffer Curve concept. The reduction in marginal tax rates led to increased economic activity. Businesses had more incentive to invest and expand, which in turn led to job creation. This growth in the economy offset some of the potential revenue losses from the tax cuts, showing that the Laffer Curve principle could hold in a real - world large - scale economic situation.
In Africa, Rwanda has shown some elements of Laffer Curve success. Rwanda has been working on improving its business environment and tax policies. By offering tax incentives to certain sectors, like the technology and tourism sectors, they have seen growth in these areas. New businesses have sprung up, creating jobs and increasing economic activity. Although the tax rates are not high in these sectors compared to some other countries, the overall growth in economic output has led to an increase in tax revenues in other areas as well, such as through increased consumption taxes as more people are employed and have more disposable income.
The movie 'Trouble with the Curve' has elements drawn from real stories. However, it also takes some creative liberties to make the plot more engaging for the audience.
Trouble with the Curve is not a true story. It's a work of fiction that was written to engage and captivate the audience through an imagined narrative and characters.
I don't know which book you're referring to. However, generally speaking, the plot and character development of a novel have a certain degree of curvature, which depends on the genre of the novel, the author, the bookstore, and other factors. Some novels might add some twists and turns in the story to make the characters experience more challenges and grow up. These could be seen as a certain arc.
