My experience with Mexicans in the US is that they send to Mexico all of the surplus left after they cover their US expenses. With everything locked down, they have had no place to spend their money. Thus the amount available to send to Mexico has been large.
Consider. If there is 15% or 25% unemployment then that means there is 75% or 85% employment. We in the 75% or 85% who are employed have not been able to spend our money. The result is that there is a pent up amount of money in the 75% or 85% waiting to be spent.
Most of us have been paying down our credit card balances.
Who ever correctly anticipates what we will buy with the pent up money will become rich....unless the government determines that it is unfair to seize the opportunity.
I wouldn’t be surprised if this is also an indicator some are “cashing out” - sending everything they have before heading back down to Mexico. For some of them (especially restaurant workers), jobs won’t be coming back soon. In my area in NJ I’ve read a few stories where owners of restaurants operated by families for generations are simply closing permanently. The owner is old enough, and knows the heyday is gone for some time - people will not be going back in the numbers they had in the past for some time. Between virus fears and lack of disposable income, it will be tough here for a while.
I’ve also known a couple of people who would have worked longer decide to hang it up; working remotely is rough on them, and they’re old enough to retire.
That, and the cartels have lost their usual money laundering channels through "legitimate" Mexican owned US businesses overpaying for perfectly legitimate Mexican merchandise.
With those non-essential businesses shut down, did the cartels find another channel?
