- Migrants have to work.
- Less opportunities for citizens to find work.
- Migrants need doctors and medical care which produces more budget expenses.
- Migrants need a education which means the budget will have to increase to educate.
- Migrants produce trash which produces more garbage in land-fills, which produces more rats, roaches, flies, mosquitoes and potential diseases to spread.
- Migrants occupy homes, apartment buildings, public spaces which means less for citizens to have available to be or live in.
- Migrants need to eat, drink, buy clothes etc which consumes national resources which are limited.
- Migrants have to shower and use the bathroom which means more consumption of water resources and sewage maintenance which cost lots of money to the state and tax payers.
I seriously desire to hear from your perspective who support mass migration. Give a logical response.

14Amazing hair plus Amazing mind. Nice combo. 👌
Those smart kids hurt Mexico by leaving though. Mexico needs their brightest and smartest in their country to benefit them, not leave and help another country to prosperity.
Yeah, because migrants drive down wages. Migrants have no choice to pick whatever job is available and accept pennies for pay.
Natives will do the same jobs but with better pay, work conditions and benefits which are denied nor afford to migrants.
