Perhaps one economic factor is that, as the cost of other components has

The capacitors now stand out as the expensive components. And that's an
incentive to lower standards.

Some of them are approaching zero value. Older equipment was expected to last
10 years or more. A lot of today's junk is lucky to last a year or two. In that
respect, the costs are going up, not down. Lower grade caps are a very high
failure item. I had one C-band receiver on the bench a few years ago. It had
about 85 electrolytics, and every one was bad Most had no brand name, and some
weren't marked for temperature. It belonged to a bar, and they needed it right
away, so they paid a large bill to have it working the next day. I generally use
Panasonic and Rubicon for repairs and my projects, these days.

Near the turn of the century a Missouri man named Chris started
badcaps.net Chris' "master list" enumerates the capacitors that he
trusts:

Chris also hosts a lively forum at https://www.badcaps.net/forum/
Although its more apropos to repair.
