Wirecutter seems to "lean", where the original site, before NYT purchase, was (much) more balanced. Knowing this, I thought the blog post write-up dove tailed nicely.
From the bottom of the first page in the report:
Overall Gain – 1964-2019 .................................................... Berkshire: 2,744,062%
S&P: 19,784%
Yes, that is correct. Berkshire stock is worth 27440 times as much, in nominal dollars, as it was in 1964. Meanwhile, a hypothetical no-load S&P index fund would be worth 198 times as much, again in nominal dollars. That is why Warren Buffett became the world's richest person (for a while; later he hired Bill Gates to help him give his money away) and his shareholder letter is on the front page of HN. If you hadn't heard of him before, congratulations! You're one of today's lucky ten thousand!
