This is a nice joke, but the reality is that standard American sewage pipes are smaller in diameter than in Europe, and European toilets tend to flush with more pressure.

Most toilets in the US are created to be "green" when it comes to water usage, but the reality is it takes at least 2+ flushes most of the time instead of 1 because of it - but as long as the amount of water per flush is low it passes regulation.

In my experience, the US toilets from ~2000 to ~2005 were crap (heh), but since then they've figured out how to make a low flow toilet that works, and it's fine.

Or if they are Trump 10-15 times: https://www.youtube.com/watch?v=VygBCFQVFgM

Low flow toilets are the worst.

A good, modern low flow works better than the old high flow toilets. A few years ago I lived in a new house with a Toto low flow. It was the best toilet I've ever used.

They used to be pretty bad, but with time I think they've gotten to be just fine.

You can't cheat physics. If you dump X gal of water from Y height it will have Z kinetic energy minus efficiency losses. We've greatly improved the efficiency of the water dumping mechanism over the years but a high end low flow toilet of today is still nothing compared to a high end toilet of decades past. That said, there's a lot of crappy old toilets out there that don't flush any better than a modern low flow toilet and take 5+gal to do it.

Source: Moved into a house that was once owned by wealthy people. The upstairs toilet was clearly top of the line circa 1940s and is awesome. The downstairs toilet was clearly subject to some serious compromises for packaging reasons and is nothing special.

You most certainly can improve upon bad implementations. Kohler's most recent line (within the last 10 years) are considerably better than all toilets I've had before. They consume much less, flush once and don't make an excessive amount of noise.

Could you talk more about this? Anecdotally I've found american diets to not be fiber rich and full of fried foods, resulting in less solid BMs, but maybe you have more information?

edit: any explanation for downvotes?

I don't know why you are being downvoted by I can chime in with my own experience. I switched to a largely whole food plant based diet last year, instead of getting 1/4-1/2 of the recommend fiber intake I now get 2x+ the recommend fiber intake. My stool has gone from clay logs that often took considerable effort to pass and would stick to the porcelain to effortlessly (amost freakishly so) pass and tend to have a considerably smaller diameter that breaks up more once it is in the bowl.

My pre-whole food plant based diet bowel movements would also leave considerable residue, often requiring 4-5 different wads of toilet paper AND 2-3 wet wipes to wipe clear. Now 1-2 wads of toilet paper leave me rarely even needing a wet wipe.

Honestly it's the biggest difference I've noticed since switching to whole food plant based. Frequency of bowel movements and just how easy/clean they are, I used to regularly have to clean part of the toilet bowl where clay-poo would stick and I've not had to do it once since switching my diet. Then mu grocery bill as the bulk of my kcals come from oats/bananas/potatoes now.
