Trickle-Up EffectAdvantage - Innovations or trends start from lower or grassroots levels (e.g., everyday consumers or small communities) and move up to influence mainstream markets or higher social classes. This can lead to more authentic, diverse, and consumer-driven trends.Disadvantage - It may take longer for ideas or benefits to reach the top levels or broader markets, causing slower overall adoption or impact.Trickle-Down EffectAdvantage - Trends, benefits, or wealth start from the top (wealthy or elite) and gradually spread down to lower levels. This can quickly boost mass-market appeal and economic growth.Disadvantage - Often leads to inequality since the benefits may not fully reach lower levels, and it can perpetuate social divides or exclusivity.
