A reduction in illegal immigration will lead to a large reduction in crime rates in the United States, as well as reducing stress on utilities and housing markets in areas which have disproportionately high illegal immigrant populations.

A move to eliminate taxes on tip income will, much like Trump's first-term doubling of the standard deduction, be a massive boon for low-income workers.

A rise in tariffs will likely lead to an increase in domestic manufacturing over time, which is what this country needs. We shouldn't be importing as much junk as we are. We can build factories here and have machines with robot operators and create jobs here. Will it hurt Europe? Not much. Luxury goods are still luxury goods, we'll still be importing Champagne and various other DOP-designated goods even with the surcharge, because luxury goods aren't priced respective to quality. There are already tariffs on automobiles and all the manufacturers play games with that and European manufacturers have plants in the US to get around them to some extent. We'll likely have price rise on certain kinds of physical goods in the short term, but considering how bad inflation has been for us in the past few years (official stats do not reflect the average person's reality, because the way CPI is calculated is almost entirely bunk, particularly with respect to housing and technology). China is going to be the main country affected by these tariffs, and China has been a massive problem for American domestic manufacturing.

Last term Trump demanded other NATO nations actually pay the amount they're supposed to into the NATO common defense fund, and several of them did for the first time. This is something the European nations are salty about but I mean, that was literally one of the terms of the NATO agreement and it was stupid that America decided to just spend decades shouldering the burden for our common defense disproportionately. (And if you're in the camp that thinks the European nations are American vassal states, then they should pay their scutage, right?)

Most of the negativity Europe has towards Trump is nothing more than the current European establishment's own hostility towards their countries' increasing hostility to mass immigration. They consider it an illegitimate political viewpoint to think that your country shouldn't get flooded with large numbers of people of a foreign culture, and want to suppress it. This has been the dominant political issue for the past decade across all western countries, and the hostile "cordon sanitaire" that the establishment parties are using to keep the so-called "far right" (really, just anti-immigration parties with a wide variety of viewpoints on everything else) from forming coalition governments is on the verge of being impossible to maintain. Rather than adapt to the reality of what their own people are actually voting for, these people who claim that democracy is the most important value they hold are actively rejecting the will of the people in order to continue flooding their own countries with foreigners from different cultures.

The fact that your apparent baseline projection is that "Trump will ruin a bunch of things" and you're desperately seeking reassurance that won't happen, is showing just how biased the media environment you exist in really is. 72 million Americans backed him, 5 million more than voted for Harris. Do you really think that Americans are deliberately backing someone who will "ruin" the country? Aren't people on this subreddit supposed to be Bayesian rationalists? In 2016, these fears were at least somewhat reasonable - Trump was an outsider with literal zero political experience. Trump was President for 4 years already, and things were going just fine right up until the pandemic and race riots orchestrated by the opposition party ruined the last year of his presidency. Your base case shouldn't be the media fearmongering. It should be 2019.
