my areas facebook page is loaded with right wing ads

my wife got her first pay check this week with her new raise, she gets paid bi-weekly. the raise amounted to $40.80 and she cleared $27.25 or roughly 33% was taken for taxes.
the ad was small businesses are over taxed! I,M told by my cpa that they average closer to 13% after write offs!
corporate taxes use to pay about 50% of the taxes in 1946 they now pay one quarter of that shifting the tax burden to the public.
