RWN - Trump is asking for $6 billion this year for continuation of a border barrier, wall, fence - call it what you will. Barriers work - not 100% - nothing works 100%.
The fact is, estimates regarding the cost to American taxpayers for support/services for illegals range from approx. $50 billion to $150 billion per year - this is after estimates of illegal’s tax contribution is backed out of the costs. Forbes estimates that the cost of medical services alone for illegals is approx. $18 billion per year
The placing of your referenced “stupid wall” to assist our border patrol to impede inflow of illegals is hardly stupid. What’s stupid is this country’s continued enticement of immigrants to enter the US illegally and uninvited.
Border patrol agents, drones, electronics are all helpful, but by themselves such measures have been shown to be insufficient. Case in point: For decades the number of illegals in country was thought to be 10 to 12 million. A study last year conducted by Yale University School Of Management (hardly a bastion of conservatism) estimated our illegal population to be between 16 and 29 million. Pew Research estimates that 1 in 10 workers in Cal is in country illegally - you think that might have an impact on wages citizens are paid?
Consider this: What do you think the impact is to the schools and our school children with such a large influx of non-English speaking illegals of school age. The impact isn’t just monetary - the learning rate of the entire classroom is impacted, special teachers need to be employed, etc.
I could go on, but what’s the point.
Final point - I pretty much agree with your other points. When the bill comes due, I hope we have enough money for soup!!
