The US economy is not broadly strong; its perceived strength is almost entirely driven by a massive, concentrated bet on AI. This singular focus props up markets and growth metrics, but it conceals widespread weakness in other sectors, creating a high-stakes, fragile economic situation.
The AI boom's economic impact extends beyond direct investment. With AI plays driving 80% of stock market gains, a powerful 'wealth effect' is created. This disproportionately benefits the top 10% of earners, who in turn drive the majority of US consumer spending, fueling the broader economy.
AI's contribution to US economic growth is immense, accounting for ~60% via direct spending and indirect wealth effects. However, unlike past tech booms that inspired optimism, public sentiment is largely fearful, with most citizens wanting regulation due to job security concerns, creating a unique tension.
