LAT sensible about tax code, but inconsistent

In an editorial today, the LAT argues for a simple tax code that does only one thing: raise revenue. Good for the LAT.

The trouble is, the LAT is inconsistent. It wants simplicity but then advocates credits for energy-efficient cars and home improvements, for education, for child care, for low-income taxpayers who work, etc. These are the kinds of things that make the code complicated. The LAT can't have it both ways.
