I'd love to agree that STEM students make a large contribution to society, but your suggestion that there is some linear relationship between what people are paid (note: paid, not earn) and their contribution to society seems flawed. There are countless counter-examples and many vital but low paid jobs where the supply/demand balance (amongst other factors) suppresses wages.
The Western narrative about manufacturing is wrong, totally wrong. More STEM != manufacturing returning to the West.
More engineers != more widgets. More workers is more widget, but not all 6 years degree holding engineers are willing to work on the assembly lines.
12 years ago, we had excellent assembly line workers, because for $400-$600 per month you were able to hire a degreed engineer with some experience to work on the line. The best of them were then promoted to line, and then shift, and then factory level managers.
What's happening now? There are no workers for these engineers to manage. A $3000 per month shift manager can still live in Shenzhen, but regular workers only survive, and they leave the city. Talented people don't get to work on the line anymore, but they go for extraordinary effort to get these few $3000-per-month manager jobs remaining. We literally had cases of HR manager being bribed, forged degrees, and references.
The best indicator for long term viability of the place for manufacturing industry is the cost of living, and life prospects for an educated labourer. Cheap housing it the best way the govt can subsidise manufacturing.
12 years go, line work was a dream job for an average youth in south China: you will be able to buy a motorcycle from your first salary, get a girlfriend at the factory, pay for a tech college in 1 year, live in a free dorm space being fed, and boarded by employer, get the company pay for your certification, or upskilling course, and move out of a town in 4-5 years as a big man, or, if you are skilled. and lucky, settle in the city.
And the city was very welcoming, it was the best city in the country to be a 20 years old: cheap night life, snacks, and food for a working man on every corner. Cheap illegal dorms were overlooked, and much of the garage industry too. Motorcycle ownership was not curtailed, or looked upon as it was in the rest of the country. The inter-provincial racism was also completely unheard of, which was unique for China (Chinese distaste immigrants from inner provinces more than foreign immigrants.)
Now, there is an aura of hopelessness over the industry. Most of workers are middle age men who never managed to make it anywhere else. They are 2-4 times less productive than young, bright people we had 12 years ago.
Reason for this all: Shenzhen allowed the cost of housing to past Manhattan, and overfocused on attracting the elite managers, and went extra hostile on blue collar lifestyle.
But you are correct that the role of semis is to enable cost and efficiency savings in other industries and activities. And that not all those fields are currently taking advantage of the opportunities (and hence not passing on the benefits to their customers and the taxpayers who frequently support them).
The role of subsidies is misunderstood by Western policymakers when it comes to tech. Very often subsidies only incentivise continued overreliance on inherently more expensive, inefficient, or overkill technologies, vs. allowing a superior, cheaper alternative come.
Germany erased itself from an IT industry map by subsidising copper based telecoms.
Sematech KILLED the remaining US semis largely because they weren't pushed to move to CMOS early enough. Instead, Sematechers wasted the money on salvaging their existing process, designs, and products, or just took the money, and did nothing at all.
China began chasing USA in the high status high tech niches and abandoned its strength in down to earth manufacturing approach. Chinese manufacturers pocketed all the "high-tech" subsidies, and did an out of tact hightechisation which crippled them. I would say, Chinese indigenous "Shanzhai" tech was already dead by around 2015 on the enormous wave of subsidy receivers crowding out real innovators.
Manufacturing people invariably use government handouts as a leverage for existing business, rather than internal investments. Cashing out subsidies pay, and the investment for future would not before you are crowded out by people who were able to make a quick buck.
Only by sensible deregulation, and agile adaptability can the government benefit the business. Businesses produce value — Governments take value, and the only way the can help is by finding out how to not to destroy what's produced. Western policy making elites don't understand the concept of delayed gratification.
The biggest, and single most harmful impediment for manufacturing in the West is its legal-regulatory system being turned into a minefield.
Having said all that, I am not convinced that the current generation of "disruptive" start-ups are always the ones doing the useful and necessary work here.
Agreed. The silicon valley is a hollow cult parasitising on the ultra low rates. Stock market sucks life out of the real market.
