In an op-ed the Los Angeles Times published today, IPS associate fellow Sam Pizzigati and Phoenix tax lawyer Bob Lord pinpoint what’s truly unsustainable about the nation’s tax system. Taxes on labor are rising while taxes on wealth are declining and an increasing share of wealth isn’t subject to any taxes at all.

Pizzigati edits Too Much, the Institute for Policy Studies’ weekly publication on excess and inequality and writes a weekly column for OtherWords, the Institute’s national editorial service. Lord is an OtherWords contributor.
