That's part of planned obsolescence. Use substandard materials now, save money in the short term AND make more money in return purchases down the line.

I recently ordered some small marker lights for a friend's boat. The lights are led with the wiring coming out of a sealed plastic threaded post in the center.

The wiring is SO small and brittle that if it survives the installation process, it will definitely break down under regular electrical load, not to mention exposure to the elements.
