> Goods are usually (although not always) inferior when made by a machine.
This is only true in the beginning, when machines are still primitive (e.g. first automatic looms). Nowadays machines mostly yield much better quality than any human can produce (e.g. automated welding, anything CNC controlled). Many things are only possible to build with machines (e.g. semiconductors).
> A hand-crafted solid wood table is still superior to something from Ikea.
This is by choice. Ikea chooses to produce the cheapest furniture possible, using cheap, crappy materials. Other manufacturers still produce high quality furniture, which is much more expensive.
Ikea does sell both ends of range; its has solid wood and particle boards.
