Generally true, yet somehow if old people that end up starving along the roads aren't particularly pretty, even if you're fully supporting yourself / have planned for retirement. Basically there's a minimum of social security which is needed to avoid revolutions / plagues / extreme poverty. Plus, the way social security is built generally renders impossible any direct abolishment, since funds for current pensioners are gathered from current workers (otherwise the 1st generation of people with social security would end up paying for it without getting anything in return). Even "slow" abolishment is quite complicated, because for a time-bracket of 10 years a relatively large part of the population might end up starving / have to be supported by their families. Which would mean less mobility for young / middle-aged people, which generally decreases productivity.
