@evan An aside, but it never ceases to amaze me how totally essentially all modern notions of domestic federal welfare power rest on the Interstate Commerce Clause. A result it clearly wasn't actually intended to produce.
To be clear, I fully support the Freedom of Choice Act (and fair labor standards, and medical leave, and occupational safety standards, and union rights, and civil rights, and disability protections, and on and on…). It just shows how out of date our constitution is.
