The expensive saws in the US come with good guards. However there is no way you can put a $300 guard on a saw and sell the whole saw for $100. Thus cheap saws get cheap guards that get removed (if they are even installed). Stick with hand tools until you can afford the expensive saws with good guards is my advice.

The above is about table saws. There are other power saws you should consider instead that are cheap and work. However there is a reason the table saw is considered the king of so many woodshops and until you get a good one you will be compromising ability to do some common jobs. Just because everything can be done with a rock to high doesn't mean most people are willing to do that and I don't blame them: a table saw should be in your plans or shop if you are a woodworker.
