Tariffs increase the costs= inflation
No politician will increase tariffs in an election year unless it fills their pocket and they plan on leaving office.
That is also true, but I believe things have changed. I think the overriding reason this year is to get elected/stay elected by any means. The rise of authoritarianism requires continuity. Appeal to our lack of taking the time to actually become informed about things and instead react emotionally to misinformation and outright crap being spewed from all corners.
Nobody tries to surreptitiously manipulate us any more, they just flat-out say "Do this, you idiots. And don't bitch about it - you can't change things anyway. We know what's best."
As far as inflation goes - we led a very charmed life there for a long time. The low-hanging fruit of easily extracted/plentiful raw materials and resources is swiftly drawing to a close. Things are catching up to that and we are paying more.
Since we can't as a society pull our heads out and collectively fix the big stuff, you are left to your own devices to do what you can individually. But that's what the forum is all about ;-)
(sorry about going off-track here - I guess this belongs in chit-chat. I will shut up.)
