This has all your answers . And more <| sep |> It ' s pretty common in the Subaru world , even for non turbo engines . Lack of care , design flaws in older headgaskets , etc . <| sep |> I ' m in the plaza now <| sep |> Alabama could y ' all stop pls <| sep |> Palestrina , while I agree with most of your posts , I would like to play devils advocate here . In many cultures and countries outside of northamerica the norm is to live in a multigenerational household . This has financial benefits and strains the healthcare system less aging at home , studies show this also helps things like depression , dementia , alzheimers . There are many immigrant families that are thriving because of being able to live in this arrangement successfully . I often see very large homes that would be comfortable for a multigenerational household grandparents , parents , children that are easily afforded with a higher household income due to more people . Often times these considerations are made for cultural reasons first and for financial reasons second though there is definitely huge financial benefit . That being said , it would be dumb for that full time working individual not to contribute to household expenses or a amplified savings rate .
