I wouldn't make it a requirement. I am distinctly uncomfortable with the precedent it sets and how future legislators and lawyers might leverage that precedent. 'Slippery slope' is often considered a fallacy, but our nation has historically used previously established, tangentially-related precedents to push new policies well outside the original scope; when it comes to law in the US, I feel that a certain measure of 'slippery slope' paranoia is justified.

That said- I would support the idea of repaying kind in kind; individuals who have donated blood should have a higher priority for blood donations. Similarly, I would support prioritizing registered organ donors on organ transplant waiting lists. Of course, it wouldn't be quite as simple as 'donors first,' so much as donor status being a factor in the prioritization; all else being equal, the donor would get first dibs, but all else is rarely equal, eg. severity of the need would still factor in; a non-donor with two failed kidneys could be given priority over a donor with one failed kidney and one partially-functional kidney.

If we're entitled to anything in this country, it should be our own blood. No way one should be required to give blood, that goes perfectly with the implications that one should be required to help if they have the means to, and I also disagree with that idea.

While I am all for having more blood reserves in the hospital, I will have to say that it is a responsibility too big for the current state of the country.

You cannot just gather blood from the masses.

First and foremost, you must ensure that the blood that you received will be stored in a good shelf. The current amount money that blood banks consumes already racks by millions. Now imagine how much would be spent if every single person would donate blood?

Second, think of the maintenance. Supposedly that the state found a way to gather enough money, you must also remember that it takes a lot of manpower to check every single storage. And that's not all. An average pack of blood has an average shelf life of 2 years, which means that people has to donate blood every year to replace all those that cannot be used anymore, which means that more doctors are needed to accommodate the people. We do not even have enough doctors in hospital, let alone add more in blood banks.

I would love to have more blood in our blood banks, but I don't think that we have enough technology to resolve that, yet

While it is extremely generous and helpful to give blood, it SHOULDN'T be a forced decision. Giving blood should and is a choice. Some people are just uncomfortable with needles and some people probably cannot give blood due to medical reasons.

Blood donations are donations; not requirements. No one should be compelled to donate blood.
