Just FYI but studies say that the poorer a kid is the more likely they are to go out of their way to dress in designer clothes and buy expensive things to hide the fact that they are poor to their peers, and this produces poorer outcomes when it comes to their education as they prioritise paid work and other activities aside from their own education to pay for these things. This leads to poorer academic results and dropping out of school to pursue paid work at the expense of their long-term future.
Self-expression and freedom is great but not in every circumstance.
