It seems so damn simple

For years I lived along the Mexican/US border.  One time was in El Paso, TX where I was in the service, found my lovely wife of 46 years and our first daughter was born.  Part of the time I was a student at UT El Paso, go Miners.  My wife and I would spend a lot of time in Juarez Mexico for all sorts of things.  We bought groceries, went to dinner and dancing, the museums and sight seeing.  Juarez was a great city with great people, wonderful culture and a rich heritage.
As mentioned I went to college in El Paso.  There was one particular parking lot I used at the university that overlooked the Rio Grande down towards Smeltertown.  Almost every morning there was a Border Patrol car parked there watching the people wading across the river from Mexico to El Paso.  They were just watching to see who was coming across.  What all the crossers looked like were people coming over to do various day jobs or housekeepers or whatever.  They would get on a bus to wherever they were working in town and at night take the bus back to a border crossing and walk across the bridge to their home in Juarez.
Illegal immigration didn't seem that big of a problem, all people wanted to do was make more money than they could in Mexico and live at home with their families.  It was no big deal, no problems.
Occasionally you would see the white Boarder Patrol bus (bars in the windows like the Sheriff) full of people that for some reason were not welcome in the USA drive to the border crossing the doors would open and the people on it were headed South back into Mexico.  There were men mostly but also women and children on those bus's.
It was a good system.  No one came to the US for benefits because they didn't get any.  No one came for free college tuition because they didn't get it.  No one came to stay because they might get a one way ticket on the white bus forfeiting what they had acquired by illegal immigration.  No one came for anything but temporary work and then they went home.  Some women would come in to have their baby so it was an American citizen but overall, yes, it was a good system.
What ever happened to a good way of doing things?  Nobody is taken back or deported, well, they might be deported but all that means is they are just let out the courthouse door and it's 'assumed' they will somehow go back to where they were deported to.  Why have we let the system corrupt to a point where people who are caught coming in to this Country illegally are given what they came here for?
Instead of putting them on the white bus and hauling them back to the nearest border crossing and headed South they are flown to some far away American city and given all the rights's privileges and benefits of a US citizen.  It doesn't make any sense does it?  You can build a huge fence, or a moat full of alligators, mine field or whatever you want, as long as the benefits are worth the risk people will figure out a way.  What will keep people from coming in illegally and staying is, if there is NO reason to and the only reward was a one way ticket on the white bus.  I am the product of legal immigrants.  I am not against legal immigration the country needs a fair immigration policy and the immigrants it would produce.  I have friends all over the country that are sons and daughters of legal immigrants and they are as proud an American as am I.  Immigrations is not the problem the problem is illegal immigration.  By using some common sense and electing politicians who don't ride the swing back and forth trying to keep up with the way the wind is blowing it could be solved.
