Recent experimental and theoretical determinations of (g-2)_muon, Omega*h^2 and BF(b->s,gamma) place exceedingly tight constraints on the minimal supergravity (mSUGRA) model. We advocate relaxing the generational universality of mSUGRA, so that GUT scale third generation scalar masses are greater than the (degenerate) first and second generation scalar masses (a normal scalar mass hierarchy (NMH)). The non-degeneracy allows for a reconciliation of all the above constraints, and also respects FCNC limits from B_d-B_dbar mixing and b -> s,gamma. The NMH SUGRA model leads to the prediction of relatively light first and second generation sleptons. This yields large rates for multilepton collider signatures at the CERN LHC and also possibly at the Fermilab Tevatron. The spectrum of light sleptons should be accessible to a sqrt{s}=0.5-1TeV linear e^+e^-$ collider.
