Similar story although I haven't purchased a macbook yet. Used to purchase laptops within the 500AUD range which would break or die within a year, decided to spend 1000AUD on a Asus zenbook and it's held up quite nicely over 3 years - only issue being the battery but that's expected.
Haven't spent anything close to a MBP but I know people still using the 2015 model and holding up nicely. I guess price sort of correlates to build quality? Although same can't be said for resale value.
