Middle class entitlements are economically inefficient, certainly. Not because they "take money out of the economy", the money recirculates through the economy as always, but because they direct real resources to overproviding some categories of services without regard to the price or efficiency with which those services are provided. It is not the money that matters in that, it is the real capital and the time and effort of people moved to that sector, from others. The efficiency cost in that in the short run is not large, a order of magnitude or two smaller than the amounts spent. Sustained over the long term, though, it shows up as galloping prices in the subsidized demand sectors and an increase in their share of GDP, which reduces net wealth approximately in proportion of that increase. Here that means something like 5% of our wealth wasted overpaying for health care inefficiently.
The other main effect of middle class entitlements is to reduce the savings rate. Men live on less private savings relying on government, and that lets them live a little higher, a year or two ahead of where they'd be without it, no more than that. At the cost of imported capital and service to pay for it, or slower capital accumulation, compared to what would be possible with a higher savings rate.
The programs were designed for that savings-suppressing effect at a time when many economists wrongly thought savings harmful for suppressing immediate demand, which was a dumb short term view. In reality it was prompted by an inaccurate theory about income from capital, which economists have long since corrected. The programs remain entrenched politically anyway.
And no, I never said any of it is without economic consequence. I said pretending the size of unfunded entitlements can "bankrupt" us is nonsense and one entry accounting, and it is. It is economic ignorance or preying on it; I heartily believe the former. I don't think Beck knows enough economics to find his backside in the dark.
You sound like you're reading that out of an economics textbook. You don't seem to have any grasp or consideration of the effects of government dependence, and seem to think that having your financial affairs and decisions handled by big centralized bureaucracies is, more or less, just as good as doing it yourself.
Do you work for the government?
