That's not really what I meant. Saving money and having an emergency fund is absolutely a wise idea, I only meant that it is not a substitute for health insurance, even a modest procedure can easily wipe out a savings account if you are not insured.
Obviously also there is no perfect place to live, everywhere has advantages and disadvantages, but I am still annoyed that the country I live in gets so many things right and then totally drops the ball with this. If we had a functional national health insurance system that would take care of the only really major gripe I have, everything else I can deal with. Unfortunately the only people really willing to fix the healthcare situation are also totally nuts, and I know from experience that if they do ever have the chance to revamp the system they will find a way to screw it up horribly instead of copying what works from elsewhere.
Something that the more liberal wing of politicians neglect to mention is that people tend to spend as much money on rent or housing as they are comfortable spending. So for instance they might spend up to 40-50% of their take home on rent to live in a good area. So the politicians go, "We need better wages and lower rent!" Well you can't have both, because rents
will track wages, as will house prices, if you pay say $30 an hour to work in a Starbucks then all of the apartments nearby will be more expensive. And neither can you impose a restriction on rents because you haven't solved the fundamental problem of excessive demand, now you've just created a waiting list for housing.
And no politician wants to go and say, "Well maybe you shouldn't rent that $1,500 apartment but get that $900 one in that sketchy area" because their constituent is above thinking they are anything other than one to live in the nice part of town, with all the nice shops and parks that they want to live near.
Perhaps the only way to deal this is to literally enshrine in law "you can only spend 33% of your take home on rent" - that would limit rental inflation but create all sorts of headaches for housemates living together, people with erratic income or the self employed, and there would no doubt still be corruption.
Longer term better public transport makes cities more livable so the practical area of a commute becomes larger, as well as arrangements like working from home for jobs that can accommodate that.
