Couldn't agree more, but it's more complicated than that. Usually if something isn't pegged to inflation via CPI some politician(s) had a reason for that.
As an example, say Party A wants to raise the minimum wage but party B wants it lowered or the same. They agree to raise the wage, but don't adjust it annually for inflation. Party A "wins" but every year party B "wins" more and more, as long as it isn't adjusted upward further.
An interesting recent example is in the House Republican's tax cut bill. The thresholds for which tax bracket you would fit in are adjusted annually, as they are now, but would be done via chained CPI[1]. Chained CPI grows more slowly, thus meaning that over time, people get pushed toward higher brackets, subtly increasing tax revenues.
