Thanks for the suggestions, Zim. And I will look into those.
But I was thinking more of the companies, higher up the pecking order, which enable industrialization and building of other machines and tools. So snap-on builds their tools with WHAT tools? That is where I think the big money is likely to lie, as it is the bottleneck to re-industrialization.
Which reminds me of a quote:
“Men have become the tools of their tools. Money is not required to buy one necessity of the soul. Most of the luxuries and many of the so-called comforts of life are not only not indispensable, but positive hindrances to the elevation of mankind.”
― Henry David Thoreau
