Poor quality jeans

I bought 6 pairs of Levi's jeans a few months back and its actually shocking how poor the quality is. Three of them are beginning to tear between the legs and crotch area and I am not even wearing them that often. They are so expensive for one pair and I might as well buy a different or cheaper brand if this is the quality of them now. I have been wearing the Levi's jeans for 20 years now and the quality is deffinitely becoming poorer and poorer
