mazal,
you can make yourself feel better about it without the need to knock others. For example, your case of preparing for shabbos by doing the cleaning yourself for shabbos that is a bigger mitzvah than having someone else do it, (the gemara says this explicitly), so it should make you feel better about not being able to hire cleaning help. But why do you need to be judgemental of those that do hire cleaning help? You don’t know their situations and nisyonos so why judge them? Same with a bigger house, fancier stuff, you should feel proud of yourself for being satisfied with less gashmiyus without knocking those that have more.
