goodness... where do you live lol... I hope it's not in the US or it really a grim picture you are painting.
sky high debt - pls study the monetary system.... debt = money supply.
dependency on foreigners - that's a bad thing? we are attracting the brightest people to become US citizens.. a tremendous talent pull world wide.
infrastructure - yes its pretty bad - give Trump some time... 3 years he has been working non stop, will get to it.
society deeply divided - perhaps, but it might just feel this way - deep division periods did happen in the past... also how do you drain the DC swamp without disrupting it..
mediocre products - this is nonsense.. a certain country's economy is more or less competitive in different industries...
