While not a goal per se (as rationalized by the other respondents), I'd argue that unbridled (i.e. without external controls or regulatory strictures) capitalism will ultimately devolve into fascism where, through mergers, acquisitions, anticompetitive behaviors, etc., a single entity would become the sole source for all products and services, and government would operate as its marketing arm.
To be clear, while I do understand that capitalism is an economic principle rather than a form of government, my supposition is based upon observations of recent U.S. history which suggest that the U.S. form of representative democracy is swiftly being replaced by a plutocracy.
And as power is concentrated into fewer and fewer entities, without the checks provided by governmental regulation, the logical result of this process would be a single commercial entity that has completely captured the means of production and through its total control over the market, supplanted a plutocracy shared among a few entities with a single source of power and control, a fascist "uber-corporation".
"Capitalism degenerates into fascism when the precarious ally with the
powerful to dominate the powerless. - Umair Harque (Why) Capitalism
Of particular interest to me (and from which I partially reached my supposition) is Thomas Piketty's 2013 book Le Capital au XXIe siècle (the 2014 English translation of which is titled "Capital in the Twenty-First Century") which has garnered much interest and commentary:
"That is why Piketty has made such a huge impact: He has starkly and
convincingly outlined the stakes for future generations. Either we'll
have a new birth of reformed capitalism, with his preferred
progressive wealth tax and other institutions, or we'll have wealth
concentration on such a colossal scale that it will threaten the
democratic order." - Ryan Cooper Why everyone is talking about Thomas Piketty's
Capital in the Twenty-First
"At a time when the concentration of wealth and income in the hands of
a few has resurfaced as a central political issue, Piketty doesn’t
just offer invaluable documentation of what is happening, with
unmatched historical depth. He also offers what amounts to a unified
field theory of inequality, one that integrates economic growth, the
distribution of income between capital and labor, and the distribution
of wealth and income among individuals into a single frame. ...
Capital in the Twenty-First Century is an extremely important book on
all fronts. Piketty has transformed our economic discourse; we’ll
never talk about wealth and inequality the same way we used to." -
Paul Krugman Why We’re in a New Gilded Age
"Will the world of 2050 or 2100,” Piketty asks, “be owned by traders,
top managers, and the superrich, or will it belong to the oil
producing countries or the Bank of China?” Actually, the answer
doesn’t much matter. Whatever the exact makeup of this global
plutocracy, democratic capitalism will be replaced by something more
like Putin’s or Xi’s cronyist authoritarianism — unless populist
progressive forces can implement a global wealth tax ASAP. And if that
can’t happen right away, 80 percent top income-tax rates would be a
solid first step. - James Pethokoukis The New
And Martin Gilens and Benjamin I. Page's Testing Theories of American Politics: Elites, Interest Groups, and Average Citizens:
"If policymaking is dominated by powerful business organizations and a
small number of affluent Americans, then America’s claims to being a
democratic society are seriously threatened."
And finally, this alarming quote from a scion of the "new economy" which seems to invoke the spectre of fascism:
"The fate of our world may depend on the effort of a single person who
builds or propagates the machinery of freedom that makes the world
safe for capitalism." - Peter Thiel The Education of a
