Whilst I do agree with you on that, there’s not much future survival if you don’t up your income. Living within meager means is no sort of life, it’s also unambitious. So it’s a balancing act, but certainly shouldn’t only be done with the view of living within current constraints. That’s all I was saying.
Living within your means has nothing to do with not increasing your income... Live the lifestyle you can afford now (and by afford I mean don't have to go into debt to sustain). Once you start earning more, you can add additional luxuries. Always with the caveat that you should not go into debt to do so (with the exception of buying property and maybe a car, although the car will be debated at length here).
