Is league of legends targeting people on purpose setting you up for failure just to play more??

This is the issue I lost rank gold 5 and went to silver 1 no warning what so ever plus being matched with lower ellows. I got back to gold 5 again matched with mostly silver bronze carrying. I literally got to up to gold five promos and had a bad streak it seems you never win 4 plus games my experience. I lost a lot but still mostly bronze and silver players feeding. Then out of no where I get demoted to silver like nothing after just getting to gold 5 after losing couple of games at 0. I feel like I'm being set for failure not perfect but but dam getting stuck with lanes feeding what can I do but be positive. When it comes down to it I literally got demoted from gold 5 right after getting in it minus the horrible match making getting stuck with.
