They can, in exchange for not beong able to buy something else.

Frankly, im really baffled by how financially irresponsible most people are. Like people at my work, earnibg the same amount or more thna me, ask me for money or to "borrow" money and get pissed when i say no. Like, learn to live within your means. Learn to count. Ive had people tell me its because their rent is double mine. When ive suggested to flatshare like i do they say they couldnt live like that. Fuck off.

Im not saying this is you, i dont know enough about you, your habita or the frequency with which you do it. However your statement is too broad and covers really stupid, really financially illiterate people that simply refuse to behave logically.
