Good, fast, or cheap. Choose any two.
Factory methods like pocket holes, screws, and even finger-joints are good enough for mass market construction without having to hire journeymen carpenters. This is how furniture can be made as cheaply as it is. This is just a fact of modern globalism. This is the only way to offer furniture to a global market at scale for the prices you see.
The item price you are seeing has more to do with the cost of fuel to send it in a container ship from the factory and truck it to the warehouse and then to the showroom. Then, it is the showroom labour and fixed costs like electricity and rent that drive the rest of the cost. Even if this showroom had it marked up to some ridiculous amount, just wait a few months (or go to another showroom) and discounts of well over 75% can be expected. The material and labour is not the major cost here.
Remember that the only way to send this stuff around the world cheaply is if you can minimize mass and (more importantly) volume. I assure you that this furniture was assembled by the store, or someone working for the store. And the only way to allow for that effectively and cheaply is to use screw-and-dowel construction or something similar.
If this stuff was made with more traditional joinery and mostly solid wood of any decent variety I guarantee you that the cost would be much, much higher. Because trained expertise, commercial labour, and good materials are very expensive. And if you have to buy diesel fuel by the tonne you start to notice small costs in mass and volume at scale.
There are ways to minimize the look of pocket screw construction to some degree, but it is always a trade-off. It's fine for factories and weekend warriors who want to build with sheet-goods. Glue and pocket-hole construction with some careful prep before finishing is perfectly fine in most cases.
The decision you have to make is whether or not you want to trade your time for money to make your own furniture. You have to decide what sort of material costs you want to spend, and how much time you have to complete the project. As hobbyists, we often disregard our labour because we aren't in it for the money. But this is also why it isn't easy to directly compare traditional woodworking and global factory techniques.
Or why, if you asked a local woodworker to make a similar piece out of solid wood and good veneer using more traditional joinery, even their cheapest price would make your eyes water because their labour isn't cheap (nor should it be). You might be able to find one of those local factories, where they hire semi-retired craftspeople so most of your cost is the material (we have one of those in my area). But you will wait a month or so for delivery, you will pay for delivery, and you will probably get decent, but not great, fit and finish.
