food bill is a bit of a chunk of the inelastic spend, but really the biggest one is rent... best to go as far away as you can from the center of a town to find cheaper stuff, and maybe even put up with a slightly less secure neighbourhood, since you aren't gonna fill the house with desirable, marketable items for burglars
i always found it completely unacceptable that in Australia typical rent cost was 1/4-1/2 of your baseline income, and i struggled to get work in australia because of the combination of the welfare system and the excessive costs of accommodation and having rebelled against an increasingly tyrannical education system at the time i was finishing to get my university entry score (i got OP 15, enough to get into general sciences but not CS, which required a minimum 9) - and that all happened due mainly to one pivotal event where an english teacher specifically started to target me with the use of an early form of social credit score system they introduced just as i got to year 11
at first it made me drop out altogether because i excelled at sciences and arts but i almost always was late handing in my english assignments because they were so brain meltingly retarded, both the content we were supposed to absorb to do it, and the subject matter in the case of creative or other types of writing
note that i was also able to touch type by this time... i could churn out text faster than anyone else in my class but i just had no mind to concoct the kind of trite garbage that i was expected to write
