The 30/30/30/10 model isn't realistic for most people!

I just read an article in which the 30/30/30/10 model is recommended for how you think of your money. What does it mean?

It means that you spend 30% of your income on your daily needs and bills. The next 30% is spent on investments, and the third 30% is spent on pension savings. The last 10% is set aside for emergency costs.

Well, that sounds all wise and nice, but I believe the reality for most people on earth is that 80%-90% goes to pay for their daily needs and bills. In other words, they have no money left to set aside for investments or pension funds, and the problem is that they cannot really set aside for emergency costs either. That is why people often take horrible loans to fix a car or fix other unexpected costs, because they don't have anything set aside for such cases.

What is the thing? Prices are too high and wages are too low in most countries worldwide. There are, of course, exceptions, but the problem is still a real one. What's it like where you live?
