Not true in Nevada and a handful of other states.
Any third felony can mean a sentence of up to 20 years, and any fourth felony can mean life without the possibility of parole [1]. What's worse is that many cases contain multiple counts. Under Nevada law, these are considered separate felony convictions if they occurred on different days. For example, someone that pleads guilty to three counts of car theft that occurred over the course of a few months, serves their time, and is released, is now eligible for a life-without-parole sentence if they are convicted of any felony in the future - despite having only been arrested and convicted once before.
As you might expect with such a draconian law, approximately 1 in 5 prisoners in Nevada are serving a life sentence.
