The US has massively increased the amount of testing it's doing. It has some of the most widespread testing out there. Your media just kept on continually moving the goalposts on testing for stupid, partisan reasons whilst intentionally misleading you all about how America compared to the rest of the world.
Not easily. One of the ways the media maintains this illusion is by carefully avoiding comparing coronavirus testing per-capita once the US figures became too good. For example, if you Google for this you'll only find articles from mid-May like this one: https://edition.cnn.com/2020/05/12/health/us-coronavirus-tes... and even those carefully only compare to the countries which had more tests per capita in order to push the narrative the US is far behind everyone else.
Looking at the chart at https://www.worldometers.info/coronavirus/, the US is 27th, with most of the countries above it being much smaller ones which are not an apples-to-apples comparison because there's more of them to cherry-pick and the wealthiest few can massively increase their per-capita numbers just by ponying up money and buying a disproportionately large share of global supply of consumables. The only large countries above the US are Russia (extremely fishy), the UK (whose press has been pushing about as hard on the narrative that our testing is behind the rest of the world as the US media has), and Spain. About a quarter of the countries above the US on the list don't even have 100k people, and only the ones I listed have much above 10 million. (New York State - population 19 million - would also easily beat the UK, Russia and Spain if it were a country.) It's also well ahead of the well-publicised testing success stories like South Korea and Germany.
Incidentally, the US was one of the countries the UK press used to point at in order to convince us that our coronavirus testing was falling masssively behind the rest of the world and our government was failing us.
