Oñe way poorer people can be helped is by making public transport free, or much cheaper and affordable. Here in Mallorca, public transport is "gratis," because public transport is a service and not a profit making machine. The cost.comes out of thepublic purse, the coffers of which are boosted by tourists paying a tax!
Nothing is ever free. The working population will end up paying for the services out of their pay cheques either through taxes or inflation.
But yes; spending money on infrastructure within the country would be a much better use of public funds than what they currently spend it on.
