The real wealth is made by investing and compounding the gains.
Making a budget and sticking to it is as important, because if some keeps spending more money than what they earn, the vicious circle won't be broken.
Third... other sources of income, passive income (dividends) or low demanding side hustle is what will make you have that spare money at the beginning to get out of the rat race.
But as stated above... "When is it enough, because we as humans we always want more... even if a 5usd t-shirt is good for clothes, would you spend 500usd if you had them? - Remember, if you can't afford 2 of them, then you can't afford any!)
