Answer:
The answer is status symbols.
Step-by-step explanation:
Status symbols are visible demonstrators of a person's socioeconomical status. Most of the times, the symbols are material goods.
Status symbols have changed over time. While at present expensive cars or watches may be taken as status symbols, in the past owning a large amount of books (before the printing press was invented) or wearing the colour blue (as blue pigments were expensive) were considered common status symbols.
