We show that the transition from the Wigner-Mott insulator to a heavy Fermi liquid emerges as an instability to self-doping, resembling conceptually the solid to normal liquid transition in He3. The resulting physical picture naturally explains many puzzling features of the 2D-MIT.Contribution to the Proceedings of SCES2007; 2 pages, 1 figure.Strongly Correlated ElectronsDisordered Systems and Neural Networkstext
