The US is not a nanny state and most Poles are arrogant, something Americans hate.
Americans hate competition? ;)
Some Poles think that America will find them jobs and housing when they arrive, that everybody is rich, has luxurious cars - like in the movies, but it's totally different than they imagined.
True. America ain't what it used to be. I was honestly shocked with the pile of garbage that large parts of the US are.
And why do they have to convert everything into the metric system?
Perhaps because that's the international standard, and because the US has adopted the metric system in 1866. It is used in US internal and international exchange in science and commerce.
Americans us the metric system daily:
$1 = 100 cents.
Don't you ever buy 2 liter bottles of coke?
btw.It shall be lawful throughout the United States of America to employ the weights and measures of the metric system; and no contract or dealing, or pleading in any court, shall be deemed invalid or liable to objection because the weights or measures expressed or referred to therein are weights or measures of the metric system.
(US Congress, 1866)
