You have this backwards. The current is being manufactured by demand, not manufacturing the demand. People WANT cheaper and easier.
You walk into a shoe store, you want some new everyday shoes, there are cheap and expensive versions. The pricier set has better materials for durability and comfort, and took more R&D to develop. The expensive shoes will last twice as long and be more comfortable, but are twice as expensive as the cheaper option. The pollution from each of the shoes is pretty similar. The company makes a profit of $5 from the cheap shoes, and $10 from the expensive shoe.
The shoe companies don't care which one they sell you, they want to make the most profit and both types make them the same amount of profit (you need two pairs of the cheap shoes over the life of an expensive pair)
The majority of people will buy the cheaper pair.
Did the company engineer it so that you would buy the cheaper pair and pollute more? Or is the company just forced to produce them because that's what people are choosing to buy?
There are situations and products where buying the expensive version is actually significantly CHEAPER long term, and people still choose the worst long-term option. Electric cars for example have had lower TCO (Total cost of ownership) in many areas (not all) and usage cases for a while now, and you still see people buying brand new gas vehicles. They also have a much lower lifetime environmental impact.
Again, the car company doesn't give a crap. They get their profit on every unit sold regardless. They just make what people want to buy.
You are giving companies far too much credit for how much power they have. There are exceptions of course (Cough Cigarettes Cough) where companies are being blatantly evil by doing things like manufacturing demand through addiction, but the vast majority of companies have no such capability and the most "engineering" you're going to get from them is an advertising campaign.
