Time for some education from a seasoned engineer (Youtube). There is nothing too spectacular about the table/chair, just a clever mechanism that increases the functionality of the item. Now, let's see where and how this product would fail. One, the fundi has no access to modern machines that would improve his product in terms of robustness, aesthetics, and quality. In this case, he would need a powered metal bender, a mig welder, and a mill/lathe machine to work on the hinged sections. The second cause to failure is lack of access to quality and reasonably-priced materials. The steel, wood, and paint are the lowest quality you could find anywhere in the world, and the most expensive too. What this means is that the product is utterly uncompetitive within and beyond his neighborhood. The product would not be unaffordable to the majority of people who would wish to purchase it. Actually, the target market for this product is mostly found in Karen (remnant colonialists).
Could the government be of help in such situations? Yes, it could. Unfortunately, any such initiatives would be saddled with corruption and self-interest. A few years ago, the government supplied some youths with tools they could use to set up welding workshops as a form of self-employment. The issue is that they went for the cheapest, lowest-quality machines, which were acquired at thrice the market price. Today, most of these machines are broken, the target youths are broke, and the suppliers are basking in ill-acquired monies.
