Ford did do all the above. Did unions need to fight for the same guarantees elsewhere? Sure. But the first place to get 'er done got it done through good ol' capitalism. And again, laws guarantee most of the above now, which is why unions are seen as redundant by many.
$5 an hour was such a huge wage that people flocked to Detroit like a 20th century gold rush. The equivalent today is *$66.51* an hour. http://www.dollartimes.com/inflation/dollars.php
update I'm sorry, the meme IS wrong. He raised the wage to $5 in *1914*, not 1926 as on the picture. The equivalent, with inflation, was $117.40 an hour.
