All economies are built on labor, not capital, which is nothing more than wages or labor. So your view of economics is quite warped and upside down. Your supply-side economics has destroyed our economy, devolving it from its former manufacturing, labor-built economy to one based on Wall Street and finance. Speculative trading, real estate landlordism, outsourcing..etc. We produce nothing in this country, other than debt for a small elitist class of financiers and hedge fund managers.
Every economy relies on labor, not the capitalist parasites that leech off of other people's work for a profit. Capitalism must serve the country, prioritizing providing jobs, goods, and services to the community. Any other type of capitalism is trash and destructive.
As far as innovation, that relies on universities, and plenty of public funding. The most advanced, innovative nation in the last century was National Socialist Germany, a fascist Nationalist government that forced capitalists to serve the country and funded the research and development of new technology, like rocketry, jet engines..etc.
