As a Mexican I can only agree, and would love the US to have a hard solution to this problem which a wall could certainly help. People think migrants are the US's problem but no, sadly the real question is how can we make migrants thrive in their original places and why this is not the approach to take?
In my analysis the US "War on drugs" is a major reason. Illegal goods in high demand mean smuggling and black markets with lots of profits. These markets cause criminal cartels. The cartels corrupt government and law enforcement. Corruption and cartel activity lead to high crime areas and low economic opportunity. High crime and lack of opportunity leads to people wanting to leave.
The US also ended guest worker programs that made it easy for seasonal workers to work in the US and live in Mexico. Many people wanted to do this, so they could live in their homeland with their family, friends, and culture but also seasonally work in the US where they could earn more. By ending seasonal worker programs, the people who wanted to work in the US needed to do so illegally, and, in order to minimize the risk and hassle of repeat illegal border crossings, they made a single illegal crossing and lived and worked in the US with their families.
If I were President, I'd end the drug war and decriminalize virtually all drugs. I'd also reinstate guest worker programs and make it very easy to get temporary legal access to the country. I'd invest in technology and infrastructure at the US Mexico border so we could move people through, both ways, as fast as possible. I'd also be involved with Central and South American allies and work with them to mitigate problems that may be the root of illegal immigration.
