So, we have another one of those delightful "Drug test welfare recipients" threads. I think the issue actually raises an interesting dynamic that I'd hope we could talk about outside the usual welfare state vitriol. Rather than spoil the flame-fest over there, I'll indulge the conceit of simply quoting myself here ...
It's not a nefarious plot. It's just the way it works out. Democrats push for the caretaker state, Republicans push for the police state. And once the dependency is in place, the dictating behavior part becomes compelling argument. Why should they be able to get high on taxpayer money?
We're going to start seeing the same dynamic once health care is socialized. The one thing Democrats and Republicans seem to agree on is that there's really no limit to what the government can force you to do, and once the public is picking up the tab for your health care, pretty much all your personal habits become fair game. Smoking? Poor diet? Couch potato? Look out, we're coming for you!
I think this is a genuine trend, and I see very little opposing it (outside limited numbers of libertarian rabble-rousers). Am I paranoid? Should this go in the "Conspiracy Theory" section? To reiterate, I'm not claiming it as a conspiracy, per se. No one hatched this as a deliberate policy; it's just an unfortunate side effect of our political divide.
Your concerns are plausible, but I'm not sure what evidence there is. Certainly one can point to specific areas where government control has increased over time, but I'm not sure that this is the overall trend. Industries have been deregulated. The incarceration rate appears to be leveling off. The Supreme Court has recognized new individual rights and struck down new government initiatives. A number of illegal government initiatives (eg, wiretapping by Hoover's FBI) appear to have been curtailed. Military drafts have not been enacted for a long period of time. Taxation rates have fallen significantly.
In short, it is not clear to me that overall, the government exerts more control over the individual now than it did in the past. It's also worth noting that government control is not inherently bad-- most of us recognize a limited need for taxes, regulation, and incarceration.
