As everyone has said, lossless compression might not have great ratios, but if it’s still worth it I recommend dwarfs as it creates read only mountable filesystems with minimal setup https://github.com/mhx/dwarfs

I’m really sorry to hear you have that experience that sounds awful, the concept of poor clothes doesn’t exist everywhere though so I’m not really sure what to say, I really wish I could’ve worn whatever I liked at school since I had to wear coats in summer at the cost of my health (my skin kinda sucks ngl) and the uniform they asked us to buy was so expensive and ill fitting. Again, you’ve got a different experience and I respect that.
