If you do not have the required STR for an armor, your speed is reduced by 10 I believe, but you can still wear it.Is there a limit to who can wear plate? A strength limit or something in 5e I seem to remember. Not sure how many guards will have the needed strength if so.
I checked you need 15 strength. Admitedly I have no idea how you determine stats for guards.
Ok I found guard stat block they have strength 13 so they can't use the plate mail.
Bold emphasis added. There are too many people who are unwilling to do their share and wish instead to rely on government programs for their well-being. Very true, some have little choice and offering them opportunities would turn things around, but there are many who feel entitled and don't want to be part of the workforce. Others feel you get what you earn or inherit and see no reason to give away much of their wealth to support others totally unconnected to themselves.So your belief is that it would be impossible for our world to provide sufficient resoures that everyone could have all the basics - food, shelter, water, healthcare ... the truh is that if we had an efficient allocation of resources and smoothly functioning economies with an educated and willing workforce expectation from every person, there is no reason why - globally - we could not (within a few years) provide the basics for everyone, rising everyone above what is currently considered the US poverty line.
And the current poverty line in the U.S. is WAY ABOVE what most people of the world live in. Many people in other countries subsist on a USD or two a day, but costs of food and other things are also much cheaper--it isn't a great living in most cases, but they certainly don't need the funds to be above the U.S. poverty line.
