This really has me wondering. I have always really enjoyed coffee but found tea was just not for me. Thinking back, I have only ever tried cheap shelf tea such as Lipton as you mentioned. Perhaps I need to try a real tea and see the difference. How is it a company like Lipton who aims to use the cheapest quality product success in the market?
It's the same principle as fast food. A McDonalds hamburger is very different from a "normal" burger - but it's cheaper, quicker, more standardized, and someone has to use the trimmings. There are a few edge cases who like burgers but hate McDonalds, but for most people it's close enough to be a suitable replacement.
