Virtually everyone is living paycheck to paycheck, some live a frugal lifestyle others live an extravagant lifestyle and bang it on finance hoping judgement day never arrives. Even businesses are only as good as their long term contracts and share of a market, so are not much different to people, if we are to be honest about things.
Some big name companies are still only going because they have diversified, and that's it, so working many jobs is for most people just a form of diversification in all but name, but then spreading the risk amongst employers in todays world can be a good thing, reducing exposure is common in finance and there are parallels for people as well.
Besides running a business gives you access to finance/credit which will have less impact on your personal life if things don't work out, than taking on finance/credit in your personal life and things then not working out. Most shareholders of small businesses take out a lot of money which keeps their personal finances a lot cleaner. I don't know why more people don't do it?
The only other thing is remember that the global population is still going up, so prices will continue to go up as populations in develop countries can undercut developed countries, so choose your business venture wisely for a multitude of reasons.
