Key lesson here is to not spend money faster than you make it. Due to capitalism and consumerism, a lot of people tend to overindulge and overspend on things that aren't really a necessity. One good example is coffee. You can make one at home for less than a dollar, but the younger generation tend to buy from huge coffee chains for the aesthetic appeal and to 'belong' to a certain trend. Imagine spending $5 to $10 for a coffee that you will only post on social media but not really drink it. How pathetic is that?
Those who are frugal and only spend when necessary tend to do better long-term, as they can manage to save and invest even with a small paycheck, though the investment part is another topic that can be had for this one.
And that is one of the main problems we have with our culture, spending our money is fine as that is the main reason we work so hard to get it, however many people now spend it in stuff that is useless or that it could be had very cheaply almost effortlessly, and the example you give about coffee is spot on, as this is not only about the cost, as making a good coffee is very easy as well, and yet we have a lot of people spending a lot of money over something they could have made inexpensively at their own homes.
One main reason I think that this is happening is because the power of subliminal advertising that is prevalent in the internet nowadays. Corporations get to lure you in buying their products without you ever knowing it, perhaps through the testimonial of other people or through the content that you are consuming. Something will click inside you to buy the said product because you think it will be a good buy just because other people are enjoying it.
Another reason is our concept of 'sales' in malls and stores. We think that we are getting a huge value when we buy during a sale, when in reality those are just the actual prices of the item without the markup of the store to recoup their losses. We may be getting the item at a cheaper price, but do we really need what we bought?
The mind conditioning that the media and huge corporations have imposed towards the populace is really effective in pushing us to mindlessly consume everything they produce.
Well, this is actually true on which on the era or years that we do have today on which tons of things that are new and been on sale on which in every trend then there would really be a specific price and since we do know that we do have the money then we would really be buying immediately and this is really something a very common and you would really be tempted on buying if you do have the capability.
For those people or kids who have a family which do struggle on daily needs or something that doesnt have the capacity on purchasing then they are really that in exemption but for those kids
who have a family that could be able to afford almost everything the for sure they would really be spending like a mad man.
Those kids doesnt care on what would be their tomorrow since they are really that confident that their parents would really be able to afford on buying the things that they do like.
We know that spending too much is never been good because sooner or later they would become that bankrupt but we know that there rich people or family who doesnt really
easily get go the floor despite of that mad spending just because they could really be able to sustain.
