So actually there is a case for buying stuff that looks expensive but it's actually cheaper on the long run
A prime example is the storage devices in computers, particularly SSDs. SSDs scale interestingly in price. They start out relatively cheap at 128gb and 256gb, but as you go higher in capacity, things start to get cheaper until you reach ultra high end which is up from 2 TB.
SSDs have a very peculiar scaling as technology. SSDs store bits in cells. But these cells can wear out or just snuff out over months if there is no writing happening. Therefore SSD controllers have internal code they run to rearrange data to reduce this cell wear. So here comes the problem: once you pass a certain treshold, your ssd will perform these internal writes on a large scale relative to the drive which will introduce wear but still less than what would happen if it didnt do it.
So, there is wear, and it already makes sense to buy a larger one, right?
Well, there is more. Larger SSDs are often faster and they often do that until filled for the same data as a smaller one, because SSD use a smart trick to make writes faster: they allocate some cells to be cache cells. It's simple from here, you have more cells, you can use more of them to be a cache because your drive is not full already from data
And now one I also consider to be important: environmental damage
Our SSD will wear out one day. However if we buy a large one, we pack more NAND chips on the same size of PCB. We just made less trash per capacity, just because we saved up for a larger size
So to sum it up: what seems to be expensive first may become the budget on the long run. You can use it for more time before it fails (driving the monthly costs super low), it will be faster, and it will be less environmental bother when you have to dispose it.
Data needs will only go up in the future. The first hard drive I ever dealt with was a 6GB quantum fireball. Nowadays windows asks for 20 gigabytes with a straight face. As you can imagine when your data needs will elevate over time, your smaller SSD will rake up more wear simply by being filled more relatively and it will get slower too.
You ever wondered just how better is it to be rich? Here is your proof.
This sort of scaling sort of applies around almost all computer hardware, but it's a thing in other areas too, but not this visibly.
Tools scale in a funny way. You buy some chinese shit, it usually prematurely dies from simple work, and you paid half of the price of a proper kit. You buy it again and you wish you bought the expensive one first, because not just you just made yourself available for failure again but you generated a lot more trash and lost efficiency and time just by simply dealing with equipment failure. Real professional tools like Würth, some of their lines at least, have lifetime warranty. You break it, go to them and get a new part for free.
What seems like oligarchy first is actually a high accuracy longterm purchase. When you factor costs of equipment, always do a total cost of ownership calculation. Maybe the part you deemed too expensive will be the cheapest on the long run.
On the picture you can see how the specs for the same series of drives change relatively to capacity.
