Speaking of the USA only.
1...English as the one and only language. Including the DMV, voting ballets, etc. All signs in English. Including the ones in Home Depot in Spanish for the tool section. If the lazy or stupid f*** can not figure out the word TOOLS in English, too bad. It's their responsibility to at least understand passable English, not ours.
2. Lie detectors or drug related truth sermons for political office seekers and those already in office. Public hanging if any one is lying or doing something dishonest, either Dem or Repub. It is the peoples country, not theirs to play with. Or to make laws to suit their hidden needs.
3. Have a educational system that actually is workable. The dumbing down of High school kids is child abuse of the highest order. Example: Mexican America kid's have a 55% dropout rate. Black's a little better because the boy's stay around longer to be on the sports teams. Brown or black, the girls all seem to be getting nailed at 14-15 and having baby's. Usually a dead end for them, unless grand ma ma take them over.. Let's have truth when teaching history and not the revised history put out today. The reading and writing abilities are a joke. Math is another joke.
Asian and Indians, alone with white, are the main factor right now in America. The common denominator is education, never a racial thing.
