We live, unfortunately, in a capitalist society. Ergo, our government couldn't give 2 shits about individuals, just money.
As such, their draconian measures must be viewed through a financial lens. There is absolutely no benefit for the control and or eradication of the lower earners who actually do the dogs work, then pay all of their wages to the rich who set the prices. Lockdown is the last thing they want to do. They do it because if the NHS falls over, there is a high chance of significant civil unrest. Chaos. Crime.
To what end does making the workers unemployed serve? Somebody has to do that work.
I'm sorry if you ever believed that you were truly free. We work in a cooperative society, all doing our part. The government care only for money.
