- water. Know your local sources and how to sterilise it in case something goes wrong
- education. Look into self education and extra tutoring. The government can't handle everything...
- housing. Check with family and friends. Charities and religious groups often provide shelter for the poor. Try moving (interstate or even overseas) if things are really bad locally. Plenty of people who are willing to 'house share' out there if you look
- politics. You'll need to search for this one. There are more then two parties in most countries but in reality people only
- occupation and finance. If the existing banking and finance sector you'll have to make do. Crowdfunding (https://www.indiegogo.com/, https://www.patreon.com/), friends/family, etc... Basically watch what has happened to other countries in financial difficulty and do the exact same
- realistically, the biggest problem with breaking apart from the mainstream is that the mainstream already has so much content/access? Where possible copy/keep everything you can that is good/legitimate onto any potential new network that you are to create
- be cynical but realistic. Possible though unrealistic. If the whole thing collapses (look at Europe and Latin America for good examples of even developed economies collapsing) people will stock up and attempt to profiteer like we've seen in Venezuela, Middle East, etc...
