If you define "socialism" as "social services" that's true, but that's an incorrect definition of "socialism." Literally, socialism means government ownership and control of the means of production. Using a broad brush, you might expand that to include situations where the government micro-manages private markets, such as setting prices, so as to exercise control over production.
Defined as such, the United States, and most of Europe, is further back towards "capitalism" than they were in the 1960s. In 1960, government agencies dictated what routes airlines could fly, what prices they could charge, etc. The same was true of trucking, telecom, energy, etc. Almost all of that was eliminated in the 1980s and 1990s. State-owned enterprises were privatized, utilities were deregulated, etc. The EU has consistently kept moving in that direction. Even where the government intervenes, it adopts more market-oriented approaches. In the 1930s, governments promoted universal phone service through imposing mandates on sanctioned monopolies (or state owned telecom companies). Today, countries like Sweden rely on measures like giving individuals tax breaks to build fiber. In the US, we replaced “government cheese” with SNAP debit cards.
Obviously taxation creates deadweight losses too, but that’s different, and better than direct government control over production. That’s why Milton Friedman advocated a negative income tax. He sought to replace traditional social programs—and the bureaucrats that administer them—with cash payments to the needy: https://www.nytimes.com/2006/11/23/business/23scene.html
Even from the perspective of public spending for the welfare state, in the U.K. for example public expenditures as a percentage of GDP are below the levels from the late 1950s: https://www.economicshelp.org/wp-content/uploads/2014/12/gov.... And the whole economy is much more liberal than it was back then--British Telecom is a private company, etc.
