We show that the assumption of dropping meson masses together with conventional many-body effects, implemented in the relativistic Dirac-Brueckner formalism, explains nuclear saturation. We use a microscopic model for correlated 2{pi} exchange and include the standard many-body effects on the in-medium pion propagation, which initially increase the attractive nucleon-nucleon (NN ) potential with density. For the vector meson exchanges in both the {pi}{pi} and NN sector, we assume Brown-Rho scaling which{emdash}in concert with {open_quotes}chiral{close_quotes} {pi}{pi} contact interactions{emdash}reduces the attraction at higher densities. {copyright} {ital 1999} {ital The American Physical Society}
