Lentils fall into that category of staple foods that includes rice and flour. They don't generally merit much thought because they are prevalent, yet they make up a crucial part of the diet of many in southern Asia and are popular anywhere Indian food is sold. At least, they didn't receive much thought until the Indian government banned lentil exports, which has resulted in shortages in other parts of the world, including the US. As a result, lentil prices are going up and some restaurants are turning to lentils from other countries, though "there are complaints from discerning customers who bemoan inferior quality."
The dried beans are such a staple that they are often eaten several times a day, especially by Indian vegetarians, so people have turned to hoarding them while still paying increasingly high prices. Until the ban in India is repealed, it doesn't seem like prices will be coming down any time soon. Fortunately, dried lentils keep for quite some time, so if you like lentil soups in the fall, it might be worth picking up a bag or two at the store, just in case.
