How are you reaching this conclusion while citing a graph showing the opposite? US taxes have a larger progressivity (change in GINI) effect because there is more GINI (inequality) to work with.Another chart from the same study illustrates:

Of course, one "solution" is to create a nation-wide VAT on top of the Income Tax and then, using the extra revenues, "redistribute it" to the same folks you taxed with VAT. Then US 'progressivity' would drop to European levels.
First, note that the above chart is for changes in GINI due to redistribution, the original GINI is of pre-tax, pre-transfer inequality.
Second, there is more impact from European redistribution because total taxes/transfers of benefits are larger (and in fact more broad based).
Finally, US taxes are more progressive because there is a larger difference between concentrations of tax incidence (the payers at the top) and concentrations of actual benefits (the takers at the bottom). The Kakwani index is the Concentration coefficient of cash transfers (taxes) – Concentration coefficient of market income, i.e. before taxes and transfers (Gini). This does not measure the total impact of the transfer but the 'progressvity' of the taxs and benefit transfers.
A tax is considered to be progressive when high-income groups face a higher average tax rate than low-income groups (relative progressivity). In some cases, e.g. as regards consumption taxes, high-income groups pay a higher amount of taxes than low-income groups (absolute progressivity) but still face a lower average tax rate. Taxes are then considered as regressive and the Kakwani index becomes negative. Similarly, cash
transfers are considered to be progressive when they account for a larger share of the low income groups’ income. This definition implies that flat cash transfers (e.g. a minimum pension for all) are considered to be progressive. And cash transfer programmes which benefit the rich most in absolute terms (e.g. subsidies for tertiary studies) are still considered as progressive as long as the share of these transfers in household income is lower for high-income than for low income groups. Joumard et al. (2012) provide numerical examples.
A VAT tax is less concentrated and regressive, it charges everyone who consumes anything at the same rate. If the benefits are only for the bottom quintile (e.g. Medicaid), its a more progressive tax. One of the attributes of European nations is that their heavy reliance on national VAT taxes which spreads the tax burden - in other words, if the people want a welfare state they are expected to pay for it (even in Canada, only 33 percent of the people don't pay an income tax compared to 47 percent of the US and yet Canada's' poverty rate is similar to that of the US).
