I'm not sure that's true, mate. Income tax is lower, and even state taxes (like 8.8 % in NY) still bring it in at less than the UK.
And US sales tax (5% on average) is significantly lower than VAT.
Even inheritance tax is a little more lenient in the US. Only applies to estates with a value of $12 million and above (at 40%), whereas the UK hits you with 40% inheritance tax on anything over £325,000.
Property tax is comparable to council tax but this is offset by not really having a monthly car tax.
Doesn't change your main point, however. You get fucked on healthcare (I'm typing this, incredibly bored, sat in a hospital bed in Maryland and I'm fucking dreading my bill, despite my high monthly premiums), and Social Security is only really available for exceptional circumstances.
