It is said at some point after a solider surrogate takes a shot that "these things aren't free". However, there are multiple types of surrogates, and extra abilities cost extra; therefore, there probably exist basic model of surrogates with prices equaling those of, say, small-size ordinary cars. The world's GDP per capita was estimated at around $600 in 1800, $5000 in 1995, and $10,000 in 2008 (figures in 1990 dollars). At that exponential growth rate, coupled with economies of scale associated with making billions of surrogate parts, it can be imagined that in, say, 100 years, mostly everyone would be able to afford a surrogate. However, since the movie obviously takes place in the near future, and it is clearly stated that surrogates were only introduced 14 years beforehand, the question remains unanswered.
