Not all advice is applicable to everyone. It's up to you to decide if you can and want to follow it. The advice was for young programmers and it is solid advice, but again, not applicable to everyone. It is applicable to a majority (probably even large majority). If you are young and earning a sw engineer salary it is very rare to not be able to cover your basic needs and have something left. Most people spends what is left in luxuries, lifestyle creep, etc; which is what the advice is trying to warn people about.
