i. What's the theory behind trickle-down economics?

Trickle-down economics is an economic theory that suggests that benefits provided to the wealthy will eventually "trickle down" to the rest of the population. The theory is based on the idea that the wealthy have more resources and are more likely to invest in businesses and create jobs, which in turn benefits the rest of the population.The theory is often associated with supply-side economics, which emphasizes the importance of reducing taxes and regulations to encourage economic growth. Proponents of trickle-down economics argue that reducing taxes on the wealthy will lead to increased investment and job creation, which will benefit the rest of the population.Critics of trickle-down economics argue that it is an ineffective and unfair way to stimulate economic growth, as it primarily benefits the wealthy while leaving the rest of the population behind. They argue that the theory is based on flawed assumptions and that it has been shown to be ineffective in practice.
