Economics filtered through politics and media can get silly but actual economists doing actual economics create rigorous models (like any science) and most don’t even necessarily make predictions about the future. A cross-discipline academic project on the effects of past coastal erosion might, for instance, have an ecologist, historian, and economist all write separate papers. That’s more common than pontificating on TV.
Econ is also prone to being misrepresented by politicians because there’s almost always trade-offs in the real world. Like imagine a proposed tax on gas/petrol to fund public transportation. An economist would just predict who will benefit or be harmed but you probably already know exactly what the different political parties and media outlets in your country will focus on.
