By that token, anyone who supports a war should go and fight in it, anyone who is concerned about winter fuel allowances should invite people to stay with them to keep warm, anyone who is concerned about homeless veterans should have them stay in a spare room, anyone who is worried about children being hungry should be cooking for them, anyone who is concerned about lawlessness should be patrolling the street at night etc etc etc.
We elect a government and pay tax for such things to be done on our behalf. Not to do it ourselves.
We have to have immigration as there are not enough people of working age paying taxes in this country to pay for the needs of the baby boomer generation who are now all pensioners in addition to all of our other needs as a society.
How much immigration is a debate, but unfortunately the ready supply of tens of thousands of immigrants that could come and go as they please to do all sorts of short term, temporary, seasonal work without bothering to bring their families with them has been removed by brexit. So we have to instead take people on a more permanent basis, which means families, and additional demands on infrastructure as well.
And those who come in on boats can no longer be returned easily back to the French camps many of them come from as our right to do that was also removed by Brexit.
If only it could have been predicted.
