Scripture is full of injunctions against this kind of thing, with a number of them in the book of Jeremiah. Chapter 22 verse 13 is clear enough: "Woe to him who builds his palace by unrighteousness, his upper rooms by injustice ...". But I think v15 says it most profoundly:
Does it make you a king to have more and more cedar?
On Christmas Day we celebrate the birth of a true King. Not a cedar panel in sight, nor any gold plated taps or grand marble halls. In fact no proper lodging at all, effectively ranked along with the animals just below 'peasant status' in the world's eyes. Yet it is a true King indeed, one whose reign will be characterised by righteousness and justice.
