"If the demand for home commodities should be diminished, because of the fall of rent on the part of the landlords, it will be increased in a far greater degree by the increased opulence of the commercial classes"

This quote by David Ricardo suggests that if landlords decrease the rent they charge, the need for house commodities will reduce. However, this reduction in need will be more than balanced out by the increased wealth of the commercial classes. This recommends that the commercial classes have the financial methods to acquire more home products, even if the proprietors reduce the rent. This could be useful for the economy, as it would develop more need for home products, which would in turn produce more jobs and stimulate financial growth. Eventually, Ricardo's quote suggests that the increased wealth of the commercial classes can assist to balance out any decrease in need for house commodities brought on by landlords lowering lease.
