> Also manufacturing jobs are crap
That's far too broad of a statement. You're thinking of $1/hour 2003 Chinese labor style manufacturing, or making cheap toasters for $12 / hour.
The developed world doesn't do much of that manufacturing any longer, they all shifted to high value manufacturing. Even South Korea - a more recent member of the developed club - makes its phones in Vietnam, not domestically.
The manufacturing jobs in eg Germany and the US pay moderately well in fact. The US BLS indicates total compensation for manufacturing employees averages over $39 / hour ($25.x salary, $13.x benefits).
There are a vast array of manufacturing engineering jobs that pay far better than that.
Manufacturing jobs are progressive, not regressive. They absorb large amounts of lower skill, lower education labor. They're a requirement for countries with any meaningful population base. Without those jobs, lower skilled labor tiers end up working $10-$15 / hour service jobs (in the US), typically with few benefits. Further, they often teach a trade, valuable skills, in the process. And last but not least, it's almost always critical to make things, which you can trade with the rest of the world. A high income economy can't survive on domestic barista service jobs (ie low value consumption jobs).
