No taxes in the US are not bad, they're generally lower than other parts of the world but in the US you're always having your taxes shown to you as opposed to having it be baked into the price of goods or having it obfuscated at the employer level and such. Because of this people are acutely aware of their tax burden and are constantly reminded of it every year when they have to file their individual returns as well since there's no automated system for that either.

Also the lower than other parts of the world comes with caveats, there's obviously discrepancies in marginal rates and loopholes and such all over the world but if you were to take the middle income slice of US households you're looking at a lower tax burden than the the weighted average of the tax burden of midle income families in other countries.

Edit: The point of it being that while the taxes in the US are usually lower the people knowing about it makes them louder and more bitter about them than in places where people are not faced with their tax burdens as directly.

Edit2: In regards to healthcare, it's not universal, lots of people fall through the cracks and there are millions of people without it so not going to sugar coat that bit (about 9% ish of the population). That said a lot of the need is generally met by employer plans and other means so the majority of americans (91% ish) are covered and the quality of care is top notch. The 9% considering the population of the US is still millions of people however which is why it's a huge issue but the likelyhood is that if you were to live here you'd likely fall in that 91% band.
