Hello dear developers. There is a big problem in the game - shops are more profitable than almost all industries. So it’s also unnecessary to constantly look for a bunch of cheap materials. For example, in 2 days of the game I developed up to 34k profit per day. But on the last account, I reached this amount much longer. The problem is not only profit and the difficulty of finding cheap materials. Shops require much less investment and time. Of course, you know all this, but it will still be fairer to balance. I think that it is not worth breaking the economy and increasing production profits (that is, the cost of goods), it is better to increase the cost of building stores and wage costs. Sorry for bad english.
