The funny thing is, a place that sell cheaper product is mostly expensive to live instead of a place that sell the same product but more expensive.
Just like in my country where the minimum wage is around $300, but the reality most jobs pays around $180, rent $90, the rest is for foods, transportation, health, etc which make people live from paycheck to paycheck.
While in first world countries, even people said the tax and rent cost is really high, but as long as you live frugal, you can save like 20%-30%.
Like i said, that's all relative. In here there's no minimum wage per se, but median wage for a cleaner, which is a lowest paying job, is around $2,3k /month, compared to doctors, which are paid $8,1K /month on average.
People are using up to 40% from that to rent, and especially when you have a high paying job, you need to pay higher rents because those jobs are located in cities with higher rents or then you pay for travelling.
Top of that there's an electricity and water bills, and everything else. We don't really pay for our health that much, because majority of those higher expenses are covered by taxes. But that can cost as well if you rather use private sector. And for our kids and people working in army, healthcare is just free, which is great.
But even for those cleaners earning $2.3k month, there's no other way to survive then live frugal. Some of them are barely getting by living from paycheck to paycheck as well, as price of food and other necessities has skyrocketed.
