(and I'm not implying that german politicians are the only sane ones or something. They are probably so reticent because of fear of losing an election)
Actually, the per-capita taxes in the EU are about the same as the per-capita taxes in the US. (That's dollars in taxes collected per person, not rates.)
There appear to be two differences - the per-capita GDP is much higher in the US (we have more money after taxes) and folks in the EU get better services for their money.
The latter suggests that giving the US govt more money isn't likely to be a good idea.
The "about the same" numbers are federal spending only, of which about 15% is defense for the US. US state and local govts spend a bit less than the federal govt, but more than enough to swamp the defense numbers and push the per-capita tax burden in the US well over that of the typical EU country, where the "not national" govts don't spend nearly as much.
It's typically only Labour voters (who are either public sector workers or who pay minimal tax anyway) who are happy for other people to pay more tax.
If you have followed UK election history you would be well aware that in last election the Lib Dems were pushing for a 50% band on higher earners (which Labour have since implemented?!?) and a local income tax to replace council tax.
The Tories on the other hand (in this election) are offering tax cuts for the middle and upper classes. They propose that inheritance tax band on estates should only start at 1 million. However the more important tax cut is around corporation tax where they propose (and my did this make me chuckle) to give a teeny saving to small businesses and a larger saving to big business. It's even more interesting that the way they phrase this (when talking to the public) is spun in such a way that doesn't reveal this interesting fact (about the saving for big businesses being bigger).
Nothing much has changed. Tories are still about tax cuts for the wealthy where Lib Dem and Labour look more at distributing wealth. Tbh ever since New Labour the Lib Dems have looked more left leaning than Labour.
Furthermore here are some choice quotes from the article you referenced:
"The Lib Dems' existing tax pledge to cut 4p off income tax would be funded by hitting the rich by taxing capital gains at the same rate as income tax and closing tax loopholes. There would also be green taxes."
"As Make it Happen says, if you are very rich you will pay more. If you are not rich you will pay less. This is a progressive liberal and distinctive message."
David Cameron of the Tories stated there would be no _further_ "giving up powers to Brussels". The other two stated that they wanted to work with Europe.
This results in no change by my reckoning.
I hope Volcker will prevail and US will get VAT finally.
My wish is that we simplify our tax system to the point where I don't need software and a tax attorney to figure out my taxes. I am not much into laws that require me to hire people / buy software to comply with (maybe, gotta love TurboTax audit insurance). I would prefer a flat-rate tax per taxpayer (skip all the marriage questions.
Please educate yourself ;)
Also I seem to recall that some foods are taxed differently depending on whether you intend to eat them in or take them away -- even for things where it makes no difference to how they package them. If you tell Pret A Manger that you're going to take your chocolate mousse away but wind up sitting down and eating it in the store, you're breaking the law. (Not sure whether that's the VAT or some other issue).
Shopping in The Netherlands where I am from is much simpler, I can keep a running tally in my head and not have to worry about getting to the register and having another X amount added on top because the local government wants their share, makes managing money so much more complicated.
My hope is that the Pentagon will get its budget slashed.
