You may be aware that Trump is talking about privatizing the USPS. But did you know that Congress was specifically authorized to establish the United States Postal Service by the Constitution? The USPS is one of the few government programs we have today that is actually in line with the Constitution. Of all the government programs to cut, the USPS shouldn't be one of them. Furthermore, there is a law specifically protecting the privacy of mail sent through the USPS. Here is a quote from a law firm (Wirth Law Office) discussing how mail delivered through USPS is in a protected class as opposed to other envelopes and parcels sent through private carriers that don't have the same privacy protections:

"First-class letters, priority mail and parcels mailed through USPS are protected by a federal law against mail tampering and against obstruction of correspondence. Federal law makes it a crime to tamper with the mail.

While pilfering drug money from packages shipped via private carrier like UPS or FedEx might result in theft charges, simply opening a first-class envelope mailed through USPS can be a felony. Other classes of mail, however, are not considered private."

From what I gather, this situation is analogous to how a social media company might claim (although many people disagree) that because they are a private company they have a right to censor speech whereas if the government censors your speech directly, they would clearly be breaking the law. Yet we've seen how the government has gotten around these laws by incentivizing social media companies to censor speech on their behalf. So if the USPS is privatized we will lose the substantial privacy protections that we had under it. I have to wonder if this is more of a motivation for the Trump administration to privatize USPS than cost savings?
