When legislators or their aides identify a promising source of revenue, that source rarely remains untapped for long. Every legislator with a new spending proposal starts eying the revenue as a potential offset for the new spending. The revenue is captured by the first or second legislator to write the revenue raiser into a realistic bill. I've seen this happen many times over the years. This particular revenue raiser is huge, larger than anything else on the radar. My conclusion: Health benefits will be taxed, far sooner than pundits expect.
