This just isn't true. First, cheap tools have always been around. I have a few that I've inherited from my grandfather and great-grandfather. They're junk and I keep them specifically to remind myself that consumer-oriented trash versions of better quality tools have always existed.
Second, Harbor Freight is the only consumer-oriented tool retailer that seems to be consistently improving their product lines. Craftsman, which was the benchmark for quality, consumer-oriented hand tools, dropped off a cliff in terms of quality around the mid- to late-2000s.
If you can afford professional-grade tools (Snap-On, Mac, Wera, Knipex, etc.) great. For the rest of us, Harbor Freight is the only retailer looking out for us. Their American- and Taiwanese-made tools are excellent. Their Chinese-made tools are good. Their Indian-made tools will get the job done, but it won't be pleasant. At least they give the consumer a range of options, unlike Snap-On, which gives you a payment plan.
