So when the poor fail to cross an additional hurdle of saving for something which shouldn't be necessary whilst not having enough money to feed themselves properly, which the wealthy don't need to worry about, or simply refuse to go through such unpleasantness in order to obeise themselves in front of the systems which oppress them, you accuse them of lacking self-discipline, and use that as an excuse to deny opportunity from them and keep participating in their oppression.
A perfect example of why suit culture is not just unpleasant, but is actively evil, and anyone ethical should help resist it.
One problem with it is that the bizarre notion that a suit is "professional" is a tool of social exclusion, and anyone wearing one where it's expected will support the notion, and hence help to exclude people who aren't interested in them or can't afford them.
Also simply just having to abandon my own personal culture and yield to a hateful culture where we judge people by arbitrary qualities of the clothing they wear is an awful feeling, and if I could do this willingly, I wouldn't be so good at demanding correctness elsewhere, and hence writing disciplined and secure code. You want to be able to be yourself at a place you'll be spending a significant proportion of your life. The suits game is wrong on multiple levels, and utterly rejecting it is part of my being.
